Feature Request: Retry if GitRepo client fails

[framctr]

Is your feature request related to a problem?

When a GitRepo is not reachable due to a maintenance (e.g., GitLab self-hosted update), Fleet fails to connect and the Fleet client does not retry, leading to a 502 error message:

Unexpected client error: unexpected requesting "https://gitlab.xyz/project.git/info/refs?service=git-upload-pack" status code: 502

To fix, we have to "Force Update" every single GitRepo.

Solution you'd like

In case of failure, Fleet retries to connect to a git endpoint.

Alternatives you've considered

Webhooks, but it would complicate the setup.

Anything else?
