Exclude / Ignore certain files or directories from repository mirroring
Problem to solve
When you setup repository mirroring, allow to exclude or ignore certain files or directories.
Further details
For example, we have an internal framework. All our repositories are forks from that framework. We want them to update automatically as the framework gets improved. But certain files should not get updated in the repositories like the README.md for example.
Proposal
Add a feature that allows the user to provide the files / directories he wants to exclude from the mirroring.
