Mirroring repositories doesn't work: 2:Fetching remote upstream failed
Problem to solve
The behavior of Git changed in 2.20.0, which now causes mirroring to fail if tags have diverged:
* The rules used by "git push" and "git fetch" to determine if a ref
can or cannot be updated were inconsistent; specifically, fetching
to update existing tags were allowed even though tags are supposed
to be unmoving anchoring points. "git fetch" was taught to forbid
updates to existing tags without the "--force" option.
We have received multiple reports related to Mirror repository functionality not working properly.

Further details
We currently have an option to force mirror changes from upstream, or allow branches to diverge. We should allow similar behavior for tags.
Proposal
- Change Overwrite diverged branches button to Overwrite diverged branches and tags
- if this button is checked, then we will use
--force
to overwrite tags if the tags have been modified in the remote
