3693: Implement the auto deletion of tasks r=dureuill a=irevoire

Fixes https://github.com/meilisearch/meilisearch/issues/3622

This PR should be the definite fix for #3622.

It adds a limit (1M) to the maximum number of tasks the task queue can hold.
Once the task queue reaches this limit (1M of tasks are in the task queue, whatever their status is), meilisearch will schedule a task deletion that tries to delete the oldest 100k tasks.
If meilisearch can't delete 100k tasks because some of them are not yet finished, it will delete as many tasks as possible.

Once the limit is reached, you're still able to register new tasks. The engine will only stop you from adding new tasks once [the other hard limit](https://github.com/meilisearch/meilisearch/pull/3659) of 10GiB of tasks is reached (that's between 5M and 15M of tasks depending on your workflow).

-------

Technically;
- We only try to schedule our task deletion when calling the tick function but before creating a new batch. This means we never enqueue a task we're not going to process ~right away.
- If our task deletion doesn't delete anything, we don't enqueue it and log a warn the user that the engine is not working properly

 Depending on the developed feature, you might need to provide a prototyped version of Meilisearch to make it easier to test by the users.
 
-The prototype name must follow this convention: `prototype-X-Y` where
-- `X` is the feature name formatted in `kebab-case`. It should not end with a single number.
-- `Y` is the version of the prototype, starting from `0`.
-
-✅ Example: `prototype-auto-resize-0`. </br>
-❌ Bad example: `auto-resize-0`: lacks the `prototype` prefix. </br>
-❌ Bad example: `prototype-auto-resize`: lacks the version suffix. </br>
-❌ Bad example: `prototype-auto-resize-0-0`: feature name ends with a single number.
-
-Steps to create a prototype:
-
-1. In your terminal, go to the last commit of your branch (the one you want to provide as a prototype).
-2. Create a tag following the convention: `git tag prototype-X-Y`
-3. Run Meilisearch and check that its launch summary features a line: `Prototype: prototype-X-Y` (you may need to switch branches and back after tagging for this to work).
-3. Push the tag: `git push origin prototype-X-Y`
-4. Check the [Docker CI](https://github.com/meilisearch/meilisearch/actions/workflows/publish-docker-images.yml) is now running.
-
-🐳 Once the CI has finished to run (~1h30), a Docker image named `prototype-X-Y` will be available on [DockerHub](https://hub.docker.com/repository/docker/getmeili/meilisearch/general). People can use it with the following command: `docker run -p 7700:7700 -v $(pwd)/meili_data:/meili_data getmeili/meilisearch:prototype-X-Y`. <br>
-More information about [how to run Meilisearch with Docker](https://docs.meilisearch.com/learn/cookbooks/docker.html#download-meilisearch-with-docker).
-
-⚙️ However, no binaries will be created. If the users do not use Docker, they can go to the `prototype-X-Y` tag in the Meilisearch repository and compile from the source code.
-
-⚠️ When sharing a prototype with users, remind them to not use it in production. Prototypes are solely for test purposes.
+This happens in two steps:
+- [Release the prototype](https://github.com/meilisearch/engine-team/blob/main/resources/prototypes.md#how-to-publish-a-prototype)
+- [Communicate about it](https://github.com/meilisearch/engine-team/blob/main/resources/prototypes.md#communication)
