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

Bring back release-v0.30.0 into release-v0.30.0-temp (final: into main) (#3145)
* 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

* Use more precise error codes/message for the task routes

+ Allow star operator in delete/cancel tasks
+ rename originalQuery to originalFilters
+ Display error/canceled_by in task view even when they are = null

+ 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

* Make clippy happy

They're a happy clip now.

* Make rustfmt happy

>:-(

* Fix Index name parsing error message to fit the specification

* Bump milli version to 0.35.1

* Fix the new error messages

* fix the error messages and add tests

* rename the error codes for the sake of consistency

* Apply suggestions from code review

Co-authored-by: Clément Renault <clement@meilisearch.com>

* reformat, sorry @kero

* Store analytics for the documents deletions

* Add a dispatch to the publish binaries workflow

* Fix publish release CI

* 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

78ffa00f98 Move index swap error handling from meilisearch-http to index-scheduler
And make index_not_found error asynchronous, since we can't know
whether the index will exist by the time the index swap task is
processed.

Improve the index-swap test to verify that future tasks are not swapped
and to test the new error messages that were introduced.
