3525: Fix phrase search containing stop words r=ManyTheFish a=ManyTheFish
# Summary
A search with a phrase containing only stop words was returning an HTTP error 500,
this PR filters the phrase containing only stop words dropping them before the search starts, a query with a phrase containing only stop words now behaves like a placeholder search.

3544: Attempt to use default vram budget for faster startup r=Kerollmops a=dureuill
# Pull Request
## Related issue
Follow-up to #3382: addresses the added startup time on Windows/macOS.
## What does this PR do?
- Attempt to skip budget calculation by using "known good values" instead
- Perform dichotomic budget calculation as fallback only when the known value is not actually good.

3538: Improve the api key of the metrics r=dureuill a=irevoire
Related to https://github.com/meilisearch/meilisearch/pull/3524#discussion_r1115903998
Update: https://github.com/meilisearch/meilisearch/issues/3523
Right after merging the PR, we changed our minds and decided to update the way we handle the API keys on the metrics route.
Now instead of bypassing all the applied rules of the API key, we forbid the usage of the `/metrics` route if you have any restrictions on the indexes.

3331: Limit the number of concurrently opened indexes r=dureuill a=dureuill
# Pull Request
## Related issue
Relevant to #1841, fixes#3382
## What does this PR do?
### User standpoint
- Limit the number of concurrently opened indexes (currently, the number of indexes that can be concurrently opened is computed at startup)
- When too many an index is opened, the least recently used one is closed and its virtual memory released.
- This allows a user to have an arbitrary number of indexes of an arbitrary size
### Implementation standpoint
- Added a LRU cache map in `index-scheduler::lru`. A more complete implementation (eg with helper functions not used here) is available but would better fit a dedicated crate.
- Use the LRU cache map in the `IndexScheduler`. To simplify the lifecycle of indexes, they are never removed from the cache when they are in the middle of a resize or delete operation. To achieve this, an intermediate `Vec` stores the UUIDs of the indexes that are in the middle of such an operation.
- Upon creating the index scheduler object, compute the total virtual memory that is adressable by using a dichotomic search on the max size of an index. Use this as a base to compute the number of indexes that can be open with 2TiB per index. If the virtual memory address space is lower than 2TiB, then only allow for 1 index of a fraction of that size.

3417: Allow multiple searches in a single request r=irevoire a=dureuill
# Pull Request
## Related issue
Fixes#3427
## What does this PR do?
### User standpoint
- Adds a new `/multi-search` entry point (not to be confused with the existing `/{index_uid}/search` entry points) that accepts a POST whose body is an object containing an array of queries.
- Each query must specify on which index it acts by providing its `indexUid`. Other parameters are identical to the one in the existing search routes (`q`, `limit`, etc.).
- The response is a JSON object containing an array of the results for each search query as if it had been performed using the `/{index_uid}/search` routes.
### Implementation standpoint
- Refactor authentication module:
- Allow tenant token to be checked even without an index in URL
- Add `meilisearch-auth` as a dependency to `index-scheduler` so as to have a working method of checking if the indexes are authorized there that takes into account both the API key and the tenant token (existing method relied on a behavior that was returning the allowed indexes from the API key as long as there weren't any tenant token)
- Make `AuthFilter` an object with invariants and so its fields are now private
- Use the methods of `AuthFilter` to know if an index is authorized rather than relying on its internal search rules.
- Make tenant token search rules optional and `None` when the `AuthFilter` was not built with a tenant token.
- Add a new `routes::index::search::multiple_search` module containing a post handler that performs the same work as the existing `routes::index::search` post handler, but in a loop.
- Add various tests
- Add authentication test suite

Toto celebrate their 25th anniversary with this blistering live concert, filmed in Amsterdam on February 25th, 2003.
