3659: stops receiving tasks once the task queue is full r=Kerollmops a=irevoire
Give 20GiB to the task queue + once 50% of the task queue is used, it blocks itself and only receives task deletion requests to ensure we never get in a state where we can’t do anything.
Also, create a new error message when we reach this case:
```
Meilisearch cannot receive write operations because the size limit of the tasks database has been reached. Please delete tasks to continue performing write operations.
```

3319: Transparently resize indexes on MaxDatabaseSizeReached errors r=Kerollmops a=dureuill
# Pull Request
## Related issue
Related to https://github.com/meilisearch/meilisearch/discussions/3280, depends on https://github.com/meilisearch/milli/pull/760
## What does this PR do?
### User standpoint
- Meilisearch no longer fails tasks that encounter the `milli::UserError(MaxDatabaseSizeReached)` error.
- Instead, these tasks are retried after increasing the maximum size allocated to the index where the failure occurred.
### Implementation standpoint
- Add `Batch::index_uid` to get the `index_uid` of a batch of task if there is one
- `IndexMapper::create_or_open_index` now takes an additional `size` argument that allows to (re)open indexes with a size different from the base `IndexScheduler::index_size` field
- `IndexScheduler::tick` now returns a `Result<TickOutcome>` instead of a `Result<usize>`. This offers more explicit control over what the behavior should be wrt the next tick.
- Add `IndexStatus::BeingResized` that contains a handle that a thread can use to await for the resize operation to complete and the index to be available again.
- Add `IndexMapper::resize_index` to increase the size of an index.
- In `IndexScheduler::tick`, intercept task batches that failed due to `MaxDatabaseSizeReached` and resize the index that caused the error, then request a new tick that will eventually handle the still enqueued task.

</details>
Mainly, these debug changes do the following:
- Set the default index size to 1MiB so that index resizes are initially frequent
- Turn some logs from info to error so that they can be displayed with `--log-level ERROR` (hiding the other infos)
- Add a long sleep between the beginning and the end of the resize so that we can observe the `BeingResized` index status (otherwise it would never come up in my tests)
## Open questions
- Is the growth factor of x2 the correct solution? For a `Vec` in memory it makes sense, but here we're manipulating quantities that are potentially in the order of 500GiBs. For bigger indexes it may make more sense to add at most e.g. 100GiB on each resize operation, avoiding big steps like 500GiB -> 1TiB.

3470: Autobatch addition and deletion r=irevoire a=irevoire
This PR adds the capability to meilisearch to batch document addition and deletion together.
Fix https://github.com/meilisearch/meilisearch/issues/3440
--------------
Things to check before merging;
- [x] What happens if we delete multiple time the same documents -> add a test
- [x] If a documentDeletion gets batched with a documentAddition but the index doesn't exist yet? It should not work

While updating the test suite I also noticed an issue with the indexed_documents value of failed task and had to update it.
I also named a bunch of snapshots that had no name sorry 😬
* Fix error code of the "duplicate index found" error
* Use the content of the ProcessingTasks in the tasks cancelation system
* Change the missing_filters error code into missing_task_filters
* WIP Introduce the invalid_task_uid error code

+ Rename task filter fields by using their plural forms
+ Prepare an error code for canceledBy filter
+ Only return global tasks if the API key action `index.*` is there
* Add canceledBy task filter
* Update tests following task API changes
* Rename original_query to original_filters everywhere
* Update more insta-snap tests

* Don't use gold but the default linker
* Always display details for the indexDeletion task
* Fix the insta tests
* refactorize the whole test suite
1. Make a call to assert_internally_consistent automatically when snapshoting the scheduler. There is no point in snapshoting something broken and expect the dumb humans to notice.
2. Replace every possible call to assert_internally_consistent by a snapshot of the scheduler. It takes as many lines and ensure we never change something without noticing in any tests ever.
3. Name every snapshots: it's easier to debug when something goes wrong and easier to review in general.
4. Stop skipping breakpoints, it's too easy to miss something. Now you must explicitely show which path is the scheduler supposed to use.
5. Add a timeout on the channel.recv, it eases the process of writing tests, now when something file you get a failure instead of a deadlock.
* rebase on release-v0.30
* makes clippy happy
* update the snapshots after a rebase
* try to remove the flakyness of the failing test
* Add more analytics on the ranking rules positions
* Update the dump test to check for the dumpUid dumpCreation task details
* send the ranking rules as a string because amplitude is too dumb to process an array as a single value
* Display a null dumpUid until we computed the dump itself on disk
* Update tests
* Check if the master key is missing before returning an error
