4445: Add subcommand to run benchmarks r=irevoire a=dureuill
# Pull Request
## Related issue
Not user-facing, no issue
## What does this PR do?
- Adds a new `cargo xtask bench` subcommand that can run one or multiple workload files and report the results to a server
- A workload file is a JSON file with a specific schema
- Refactor our use of the `vergen` crate:
- update to the beta `vergen-git2` crate
- VERGEN_GIT_SEMVER_LIGHTWEIGHT => VERGEN_GIT_DESCRIBE
- factor logic in a single `build-info` crate that is used both by meilisearch and xtask (prevents vergen variables from overriding themselves)
- checked that defining the variables by hand when no git repo is available (docker build case) still works.
- Add CI to run `cargo xtask bench`

4042: Implements the new replication parameters r=ManyTheFish a=irevoire
### This PR implements the necessary parameters for the High Availability
- [ ] Update the spec
Introduce a new CLI flag called `--experimental-replication-parameters` that changes a few behaviors in the engine:
- [The auto-deletion of tasks is disabled](https://specs.meilisearch.com/specifications/text/0060-tasks-api.html#_2-technical-details)
- Upon registering a task, you can choose its task ID by sending a new header: `TaskId: 456645`. It must be a valid number, which must be superior to the last task id ever seen.
- Add the ability to « dry-register » a task. That means meilisearch will answer to you with a valid task ID like everything went well, but won’t actually write anything in the database. To do that, you need to use the `DryRun: true` header.
----
Old prototype `prototype-custom-task-id-0`:
- Adds the capability to specify your own task ID via the `TaskId` http header
- Make the task IDs a u64 instead of a u32
