742: Add a "Criterion implementation strategy" parameter to Search r=irevoire a=loiclec
Add a parameter to search requests which determines the implementation strategy of the criteria. This can be either `set-based`, `iterative`, or `dynamic` (ie choosing between set-based or iterative at search time). See https://github.com/meilisearch/milli/issues/755 for more context about this change.

750: Fix hard-deletion of an external id that was soft-deleted and then reimported - main r=irevoire a=loiclec
# Pull Request

Fixes (when merged into meilisearch) https://github.com/meilisearch/meilisearch/issues/3021
## What does this PR do?
There was a bug happening when:
1. Documents were added
2. Some of these documents were replaced using soft-deletion
3. A deletion of another non-replaced document takes place and triggers a hard-deletion
4. Documents with the same identifiers as the replaced documents are added again
Then, search results would return duplicate documents. No crash would happen at any time (this is the reason it wasn't caught by the previous fuzz test. I have updated the new one such that it also checks the result of a placeholder search request, which then finds the bug immediately).
The cause of the bug is:
1. When a hard-deletion is triggered, we try to retrieve the external document id associated with each soft-deleted document id.
2. Then, we take this list of external document ids and remove each of them from the `ExternalDocumentsIds` structure.
3. However, this is not correct in case an existing (non-deleted) document shares the external id of a soft-deleted document.
## Implementation of the fix
1. Before we process a permanent deletion, we update the list of soft-deleted document ids.
2. Then, the permanent deletion's job is to remove the soft-deleted documents from all data structures. Therefore, to update `ExternalDocumentsIds`, we can simply call the `delete_soft_deleted_documents_ids_from_fsts` method, which is faster and simpler.
## Correctness
A unit test was added to reproduce the bug. The new fuzz test, when adjusted to check the correctness of a placeholder search, could also instantly reproduce the bug, but now does not find any other problem.

3264: Remove macos-latest and windows-latest usages r=curquiza a=curquiza
Related to https://github.com/meilisearch/meilisearch/issues/3109#issuecomment-1359151297
Remove the `macos-latest` and `windows-latest` to replace them with the specific version: this will avoid "surprises" in the future when GitHub changes the `latest` version.
This way, it will also allow us to let the documentation team know about the changes, since we will control the macOS/Windows version we support

3261: Use ubuntu-18.04 container instead of GitHub hosted actions r=curquiza a=curquiza
Related to (but does not fix totally) https://github.com/meilisearch/meilisearch/issues/3109 and https://github.com/meilisearch/product/discussions/547#discussioncomment-4109143
## For reviewers, what's the PR changes:
- Use ubuntu-latest where compiling with ubuntu-18.04 is not needed (`update-version-cargo-toml`, `fmt`, `clippy` jobs)
- Where ubuntu-18.04 is required
- Use `ubuntu-latest` as runner
- Use `ubuntu:18.04` as Docker container
- Install the required dependencies (curl and cc)
- Use `actions-rs/toolchain@v1` instead of `hecrj/setup-rust-action@master`. It's more stable and followed alternative. Plus it was easy to make it work with our container contrary to the old one. Change applied in all our CIs to be more consistent
- Remove some useless space to increase readability.

747: Soft-deletion computation no longer depends on the mapsize r=irevoire a=dureuill
# Pull Request
## Related issue
Related to https://github.com/meilisearch/meilisearch/issues/3231: After removing `--max-index-size`, the `mapsize` will always be unrelated to the actual max size the user wants for their DB, so it doesn't make sense to use these values any longer.
This implements solution 2.3 from https://github.com/meilisearch/meilisearch/issues/3231#issuecomment-1348628824
## What does this PR do?
### User-visible
- Soft-deleted are no longer deleted when there is less than 10% of the mapsize available or when they take more than 10% of the mapsize
- Instead, they are deleted when they are more soft deleted than regular documents, or when they take more than 1GiB disk space (estimated).
### Implementation standpoint
1. Adds a `DeletionStrategy` struct to replace the boolean `disable_soft_deletion` that we had up until now. This enum allows us to specify that we want "always hard", "always soft", or to use the dynamic soft-deletion strategy (default).
2. Uses the current strategy when deleting documents, with the new heuristics being used in the `DeletionStrategy::Dynamic` variant.
3. Updates the tests to use the appropriate DeletionStrategy whenever needed (one of `AlwaysHard` or `AlwaysSoft` depending on the test)
Note to reviewers: this PR is optimized for a commit-by-commit review.
