Jira 'versions' should be linked with Bitbucket 'release branches'

Now, Jira can say a version is finished, just because the issues are DONE and MERGED, but it could done it better if when a 'version' is created it can be linked with a 'release branch' in Bitbucket:

• it could detect if all issues in that fixVersion are in the corresponding 'feature branch'. Now, if by mistake you commit one of the issues to another branch, you dont get any warning
• it could detect if more issues than expected are added to that 'release branch'. It is common mistake to add more changes to a release than expected
• 'Build and release' option should be disabled if any of the above condition happens, and the 'version' must shown as incomplete and the reason (some missing issue not in the release branch, some not expect issue there)
