Niloth P c32e6f4940 integrations: Improve the branch filtering in Git-related integrations.
- Made the branch-filtering checks uniform across all the integrations,
by adding a helper function to git.py, and re-using it.
- Instead of checking if the name of the branch that generated the
event is a substring of the "branches" parameter, we now check if
there's an exact match.
For example, if there are two branches named "main" and
"release/v1.0-main", and the user wants to track pushes to only the
"release/v1.0-main" branch, they wouldn't have been able to
previously, it will always track pushes to both branches. There was no
way to filter out the smaller named branch when there were overlaps.
