4536: Limit concurrent search requests r=ManyTheFish a=irevoire
# Pull Request
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/4489
## What does this PR do?
- Adds a « search queue » that limits the number of search requests we can process at the same time and stores search requests to be processed
- Process only one search request per core/thread (we use available_parallelism)
- When the search queue is full, new search requests replace old ones **randomly**. The reason is that:
- If we serve the oldest one first, like Typesense, we give the worst performances to everyone
- If we serve the latest one, it gets too easy to DoS us (you just need to fill the queue with as many search requests as we can process simultaneously to ensure no other request will ever be processed)
- By picking the search request randomly, we give a chance to recent search requests to be processed while ensuring that we can't be owned unless they fill our queue entirely and we start returning errors 5xx
- Adds an experimental parameter to control the size of the queue
- Adds a bunch of tests to ensure the search queue works correctly
- Ensure the loop consuming the search queue is running in the health route and crashes if it’s not the case

4476: Make the `/facet-search` route use the `sortFacetValuesBy` setting r=irevoire a=Kerollmops
This PR fixes#4423 by ensuring that the `/facet-search` route uses the `sortFacetValuesBy` setting.
Note for the documentation team (to be moved in the tracking issue): Using the new `sortFacetValuesBy` setting can slow down the facet-search requests as Meilisearch iterates over the whole list of facet values and computes the count of documents on every entry. That is hardly or even impossible to optimize correctly.
### TODO
- [x] Create a custom HashMap wrapper for the facet `OrderBy` settings.
This wrapper will return the `OrderBy` setting of the facet, if not defined will use the default `*` one, and if not there either (strange) will fall back on the lexicographic one.
- [x] Create a `ValuesCollection` wrapper that implements the logic for the lexicographic and count order by.
- [x] Use it when there is no search query.
- [x] Use it when there is a search query with and without allowed typos.
- [x] Do not change the original logic, only use a wrapper.
- [x] Add tests

[Related Discord Thread](https://discord.com/channels/1006923006964154428/1211977150316683305)
## What does this PR do?
- Adds Ollama as a provider of Embeddings besides HuggingFace and OpenAI under the name `ollama`
- Adds the environment variable `MEILI_OLLAMA_URL` to set the embeddings URL of an Ollama instance with a default value of `http://localhost:11434/api/embeddings` if no variable is set
- Changes some of the structs and functions in `openai.rs` to be public so that they can be shared.
- Added more error variants for Ollama specific errors
- It uses the model `nomic-embed-text` as default, but any string value is allowed, however it won't automatically check if the model actually exists or is an embedding model
Tested against Ollama version `v0.1.27` and the `nomic-embed-text` model.

4445: Add subcommand to run benchmarks r=irevoire a=dureuill
# Pull Request
## Related issue
Not user-facing, no issue
## What does this PR do?
- Adds a new `cargo xtask bench` subcommand that can run one or multiple workload files and report the results to a server
- A workload file is a JSON file with a specific schema
- Refactor our use of the `vergen` crate:
- update to the beta `vergen-git2` crate
- VERGEN_GIT_SEMVER_LIGHTWEIGHT => VERGEN_GIT_DESCRIBE
- factor logic in a single `build-info` crate that is used both by meilisearch and xtask (prevents vergen variables from overriding themselves)
- checked that defining the variables by hand when no git repo is available (docker build case) still works.
- Add CI to run `cargo xtask bench`

4042: Implements the new replication parameters r=ManyTheFish a=irevoire
### This PR implements the necessary parameters for the High Availability
- [ ] Update the spec
Introduce a new CLI flag called `--experimental-replication-parameters` that changes a few behaviors in the engine:
- [The auto-deletion of tasks is disabled](https://specs.meilisearch.com/specifications/text/0060-tasks-api.html#_2-technical-details)
- Upon registering a task, you can choose its task ID by sending a new header: `TaskId: 456645`. It must be a valid number, which must be superior to the last task id ever seen.
- Add the ability to « dry-register » a task. That means meilisearch will answer to you with a valid task ID like everything went well, but won’t actually write anything in the database. To do that, you need to use the `DryRun: true` header.
----
Old prototype `prototype-custom-task-id-0`:
- Adds the capability to specify your own task ID via the `TaskId` http header
- Make the task IDs a u64 instead of a u32

4313: Fix document formatting performances r=Kerollmops a=ManyTheFish
reduce the formatted option list to the attributes that should be formatted,
instead of all the attributes to display.
The time to compute the `format` list scales with the number of fields to format;
cumulated with `map_leaf_values` that iterates over all the nested fields, it gives a quadratic complexity:
`d*f` where `d` is the total number of fields to display and `f` is the total number of fields to format.

4223: Update to heed 0.20 r=dureuill a=Kerollmops
This PR brings the v0.20-alpha.9 version of heed into Meilisearch 🎉 The main goal is to test it in a real environment to make the necessary changes if needed. We also want to merge it as soon as possible during the pre-release phase to ensure we catch bugs before the release.
Most of the calls to heed are the same as before, except:
- The `PolyDatabase` has been replaced with a `Database<Unspecified, Unspecified>`. We replaced the `get<T, U>()` by a `remap<T, U>().get()` calls.
- The `Database` `append(...)` method has been replaced with a `put_with_flags(PutFlags::APPEND, ...)`.
- The `RwTxn<'e, 'p>` has been simplified into a `RwTxn<'e>`.
- The `BytesEncode/Decode` traits return a `Result<_, BoxedError>` instead of an `Option<_>`.
- We no longer need to wrap and unwrap the `BEU32` integer when storing/getting them from heed.
### TODO
- [x] Create actual, simple error types instead of using strings in the codecs.
### Follow-up work
- Move the codecs into another member crate (we depend on the uuid one in the meilitool crate).
- Display the internal decoding error in the `SerializationError` internal error variant.

3942: Normalize for the search the facets values r=ManyTheFish a=Kerollmops
This PR improves and fixes the search for facet values feature. Searching for _bre_ wasn't returning facet values like _brévent_ or _brô_.
The issue was related to the fact that facets are normalized but not in the same way as the `searchableAttributes` are. We decided to normalize them further and add another intermediate database where the key is the normalized facet value, and the value is a set of the non-normalized facets. We then use these non-normalized ones to get the correct counts by fetching the associated databases.
### What's missing in this PR?
- [x] Apply the change to the whole set of `SearchForFacetValue::execute` conditions.
- [x] Factorize the code that does an intermediate normalized value fetch in a function.
- [x] Add or modify the search for facet value test.

3889: Display the total number of tasks matching a filter/query r=dureuill a=Kerollmops
This PR returns a new field on the `/tasks` routes. The `total` field exposes the total number of tasks that matches the given filter/query. It is useful to display information on a user interface and can help understand when progress is made in processing tasks, i.e., the total number of tasks on `/tasks?statuses=succeeded` will increase over time.
Fixes#3888.
- [ ] Update the specs fo the `/tasks` route.
## How have I implemented it?
I found it much easier to run two times the task filtering system. Once with the original `from` and `limit` parameters and a second time without. The second call will return the total number of tasks that match the query, not only the number of tasks on the current page.
So far, in terms of performance, there doesn't seem to be any issue. I tried different filters with something like 250k tasks. Note that there is a limit of 1M tasks in the queue.

3891: Fix the way we compute the 99th percentile r=dureuill a=Kerollmops
This PR fixes how we compute the 99th percentile by avoiding using float and doing the multiplication and divisions in the correct order avoiding going out of the buffer of timings. You can see the issue on [this rust playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021).
When there are a very small number of successful requests, the number is so tiny that the 99th percentile calculus sometimes gives an index out of the buffer. In this example, the `1`/`1.0` represent the number of timings you collected (one). As you can see, the float computation gives us the index `1.0`, with is out of a vector of only one value. This makes the engine generate a `null` value.
```rust
1 * 99 / 100 = 0 // with integers
0.99_f64 * (1.0 - 1.0) + 1.0 = 1.0 // with floats
```
