Implement Jira/Trello/Or Other Abstraction for Tickets support

Use case is that my team and me name branches according to user stories or bugs in Jira, for example:
  - ZOO-123_Make_100500_miracles
  - ZOO-124_Fix-all-bugs-and-do-not-introduce-new

This should also support link to issue outside of github (hosted Jira, in my case).
