Better search handling under heavy loads

All of the next PR should make meilisearch behave better under heavy loads:

• Only spawn one search queue in actix-web by @irevoire in https://github.com/meilisearch/meilisearch/pull/4893
• Make sure the index scheduler never stops running by @irevoire in https://github.com/meilisearch/meilisearch/pull/4896
• Explicitly drop the search permits by @irevoire in https://github.com/meilisearch/meilisearch/pull/4898
• Stop trying to process searches after one minute by @irevoire in https://github.com/meilisearch/meilisearch/pull/4899

Speed improvement 🐎

We made the autobatching of the document deletion with the document deletion by filter possible which should uncklog the task queue of the people using these two operations heavily. Meilisearch still cannot autobatch the document deletion by filter and the document addition, though.

• Autobatch document deletion by filter by @irevoire in https://github.com/meilisearch/meilisearch/pull/4901
• Do not fail the whole batch when a single document deletion by filter fails by @irevoire in https://github.com/meilisearch/meilisearch/pull/4905
