1796: Feature branch: Task store r=irevoire a=MarinPostma

# Feature branch: Task Store

## Spec todo
https://github.com/meilisearch/specifications/blob/develop/text/0060-refashion-updates-apis.md

- [x] The update resource is renamed task. The names of existing API routes are also changed to reflect this change.
- [x]    Tasks are now also accessible as an independent resource of an index. GET - /tasks; GET - /tasks/:taskUid
- [x] The task uid is not incremented by index anymore. The sequence is generated globally.
- [x] A task_not_found error is introduced.
- [x] The format of the task object is updated.
- [x] updateId becomes uid.
- [x] Attributes of an error appearing in a failed task are now contained in a dedicated error object.
- [x] type is no longer an object. It now becomes a string containing the values of its name field previously defined in the type object.
- [x] The possible values for the type field are reworked to be more clear and consistent with our naming rules.
- [x] A details object is added to contain specific information related to a task payload that was previously displayed in the type nested object. Previous number key is renamed numberOfDocuments.
- [x] An indexUid field is added to give information about the related index on which the task is performed.
- [x] duration format has been updated to express an ISO 8601 duration.
- [x] processed status changes to succeeded.
- [x] startedProcessingAt is updated to startedAt.
- [x] processedAt is updated to finishedAt.
- [x] 202 Accepted requests previously returning an updateId are now returning a summarized task object.
- [x] MEILI_MAX_UDB_SIZE env var is updated MEILI_MAX_TASK_DB_SIZE.
- [x] --max-udb-size cli option is updated to --max-task-db-size.
- [x] task object lists are now returned under a results array.
- [x] Each operation on an index (creation, update, deletion) is now asynchronous and represented by a task.

## Todo tech

- [x] Restore Snapshots
- [x] Restore dumps of documents
- [x] Implements the dump of updates
- [x] Error  handling
- [x] Fix stats
- [x] Restore the Analytics
- [x] [Add the new analytics](https://github.com/meilisearch/specifications/pull/92/files)
- [x] Fix tests
- [x] ~Deleting tasks when index is deleted (see bellow)~ see #1891 instead
- [x] Improve details for documents addition and deletion tasks
- [ ] Add integration test
- [ ] Test task store filtering
- [x] Rename `UuidStore` to `IndexMetaStore`, and simplify the trait.
- [x] Fix task store initialization: fill pending queue from hard state
- [x] Synchronously return error when creating an index with an invalid index_uid and add test
- [x] Task should be returned in decreasing uid + tests (on index task route)
- [x] Summarized task view
- [x] fix snapshot permissions
