2005: auto batching r=MarinPostma a=MarinPostma
This pr implements auto batching. The basic functioning of this is that all updates that can be batched together are batched together while the previous batch is being processed.
For now, the only updates that can be batched together are the document addition updates (both update and replace), for a single index.
The batching is disabled by default for multiple reasons:
- We need more experimentation with the scheduling techniques
- Right now, if one task fails in a batch, the whole batch fails. We need more permissive error handling when processing document indexation.
There are four CLI options, for now, to interact with how the batch is scheduled:
- `enable-autobatching`: enable the autobatching feature.
- `debounce-duration-sec`: When an update is received, wait that number of seconds before batching and performing the updates. Defaults to 0s.
- `max-batch-size`: the maximum number of tasks per batch, defaults to unlimited.
- `max-documents-per-batch`: the maximum number of documents in a batch, defaults to unlimited. The batch will always contain a least 1 task, no matter the number of documents in that task.
# Implementation
The current implementation is made of 3 major components:
## TaskStore
The `TaskStore` contains all the tasks. When a task is pushed, it is directly registered to the task store.
## Scheduler
The scheduler is in charge of making the batches. At its core, there is a `TaskQueue` and a job queue. `Job`s are always processed first. They are *volatile* tasks, that is, they don't have a TaskId and are not persisted to disk. Snapshots and dumps are examples of Jobs.
If no `Job` is available for processing, then the scheduler attempts to make a `Task` batch from the `TaskQueue`. The first step is to gather new tasks from the `TaskStore` to populate the `TaskQueue`. When this is done, we can prepare our batch. The `TaskQueue` is itself a `BinaryHeap` of `Tasklist`. Each `index_uid` is associated with a `TaskList` that contains all the updates associated with that index uid. Each `TaskList` in the `TaskQueue` is ordered by the id of its first task.
When preparing a batch, the `TaskList` at the top of the `TaskQueue` is popped, and the tasks are popped from the list to make the next batch. If there are remaining tasks in the list, the list is inserted back in the `TaskQueue`.
## UpdateLoop
The `UpdateLoop` role is to perform batch sequentially. Each time updates are pushed to the update store, the scheduler is notified, and will in turn notify the update loop that work can be performed. When notified, the update loop waits some time to wait for more incoming update and then asks the scheduler for the next batch to perform and perform it. When it is done, the status of the task is put back into the store, and the next batch is processed.

2120: Bring `stable` into `main` r=curquiza a=curquiza
I forgot to do it, tell me `@Kerollmops` or `@irevoire` if it's useful or not. I would say yes, otherwise I will have conflict when I will try to bring `main` into `stable` for the next release. Maybe I'm wrong

2068: chore(http): migrate from structopt to clap3 r=Kerollmops a=MarinPostma
migrate from structopt to clap3
This fix the long lasting issue with flags require a value, such as `--no-analytics` or `--schedule-snapshot`.
All flag arguments now take NO argument, i.e:
`meilisearch --schedule-snapshot true` becomes `meilisearch --schedule-snapshot`
as per https://docs.rs/clap/latest/clap/struct.Arg.html#method.env, the env variable is defines as:
> A false literal is n, no, f, false, off or 0. An absent environment variable will also be considered as false. Anything else will considered as true.

`@gmourier` found that the duration in the task view was not computed correctly, this pr fixes it.
`@curquiza,` I let you decide if we need to make a hotfix out of this or wait for the next release. This is not breaking.
