[Feature] Add GitLab REST API to force mirror update
Proposal
Add a GitLab REST API endpoint to force a repository / project mirror update.
At the moment, the latest documentation for GitLab 15.8 does not include a REST API endpoint to call, that would force an update / refresh operation on a configured GitLab repository mirror.
In the GitLab web UI, under the repository settings for mirroring, there is a clickable button that forces an update of a remote mirror.
My recommendation is to add a new REST API endpoint, that would allow a developer to force update a specific (or all) mirror configurations, for a given GitLab repository / project.
Here are the current docs for GitLab mirrors: https://docs.gitlab.com/ee/api/remote_mirrors.html
