Describe the solution you'd like
cekit build gitsync (or similar name) to prepare a build source and synchronise it with a git repository.

Additional context

The osbs builder does this as well as other OSBS (and related) integrations.

We are moving away from OSBS (to Konflux) and need to sync the generated sources with a git repository but not the other stuff. We can achieve it in a hacky way at the moment with --sync-only, but cannot control the git repository to which it syncs (we can automate mirroring that repository in the short to medium term but will lose access to the hard-coded repository service eventually)

Relatedly, a tekton pipeline or service or similar to invoke cekit would be even better, if it could be part of our konflux application itself.
