4126: Make the experimental route /metrics activable via HTTP r=dureuill a=braddotcoffee
# Pull Request
## Related issue
Closes#4086
## What does this PR do?
- [x] Make `/metrics` available via HTTP as described in #4086
- [x] The users can still launch Meilisearch using the `--experimental-enable-metrics` flag.
- [x] If the flag `--experimental-enable-metrics` is activated, a call to the `GET /experimental-features` route right after the launch will show `"metrics": true` even if the user has not called the `PATCH /experimental-features` route yet.
- [x] Even if the --experimental-enable-metrics flag is present at launch, calling the `PATCH /experimental-features` route with `"metrics": false` disables the experimental feature.
- [x] Update the spec
- I was unable to find docs in this repository to update about the `/experimental-features` endpoint. I'll happily update if you point me in the right direction!
## PR checklist
