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. Proving they've still got exactly what it takes to move a crowd, the band perform a mixture of medley's, solo spots, and huge hits. Tracks include \"Rosanna,\" \"Africa,\" \"Hold The Line,\" a cover of the Beatles' \"While My Guitar Gently Weeps,\" and many more.",

3482: Optimize meilisearch uffizzi build r=curquiza a=waveywaves
# Pull Request
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/3476
## What does this PR do?
even though docker cache was being used earlier for uffizzi builds, seems like the cache layers weren't persisting. This commit adds changes to move meilisearch building outside the dockerfile so that we can use the rust cache action. We are also building to the musl target so that the binary for meilisearch which is created can be used for the uffizzi ttyd image which uses alpine.
Meilisearch build time brought to 5 mins example https://github.com/waveywaves/meilisearch/actions/runs/4142776058
we also update the version of uffizzi action used here which fixes another uffizzi bug where the environments are not deployed. https://app.uffizzi.com/github.com/waveywaves/meilisearch/pull/2 was built as a part of a test for this PR and we can be sure that the deployment works well now.

3347: Enhance language detection r=irevoire a=ManyTheFish
## Summary
Some completely unrelated Languages can share the same characters, in Meilisearch we detect the Languages using `whatlang`, which works well on large texts but fails on small search queries leading to a bad segmentation and normalization of the query.
This PR now stores the Languages detected during the indexing in order to reduce the Languages list that can be detected during the search.
## Detail
- Create a 19th database mapping the scripts and the Languages detected with the documents where the Language is detected
- Fill the newly created database during indexing
- Create an allow-list with this database and pass it to Charabia
- Add a test ensuring that a Japanese request containing kanjis only is detected as Japanese and not Chinese

3496: Fix metrics feature r=irevoire a=james-2001
# Pull Request
## Related issue
Resolves: #3469
See also: #2763
## What does this PR do?
As reported the metrics feature was broken by still using and old reference to `meilisearch_auth::actions`. This commit switches to the new location, `meilisearch_types::keys::actions`.
The original issue was not *that* clear as to exactly what was broken, and the build logs have disappeared, but it seemed to just be this one line fix. If this is not the case and I've missed the mark let me know, and i'll head back to the drawing board.
