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

4532: Add `url` and `api_key` to ollama r=ManyTheFish a=dureuill
See [Usage page](https://meilisearch.notion.site/v1-8-AI-search-API-usage-135552d6e85a4a52bc7109be82aeca42#5c77ef49e78e43388c1d3d5429151357)
### Motivation
- Before this PR, the url for ollama is only read from the environment. This is a needless restriction that will be troublesome in settings where passing an environment variable is complex or impossible (e.g., the Cloud)
- Before this PR, ollama did not support an api_key. While ollama does not natively support API keys, [a common practice](https://github.com/ollama/ollama/issues/849) is to put a publicly accessible ollama server behind a proxy to support authentication.
### Skip changelog
ollama embedder was added to v1.8

4539: Don't optimize reindexing when fields contain dots r=Kerollmops a=dureuill
# Pull Request
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/4525
## What does this PR do?
- Don't try to optimize the amount of reindexing operation when nested fields are used anywhere in:
- the field distribution (e.g. a key actually contains a `.`)
- the old faceted fields
- the new faceted fields
This is because the facet distribution is not reporting on existing nested fields.
