We need jira issues to be linked to their corresponding code changes, e.g. bug report to bug fixes.

In MySQL we used to have a script, that was listening for commit emails and adding links to bugs in the bug database.

We can do the same with Jira.

• better to listen not for commits (as not everyone is sending them and not all commits may end up being pushed), but directly for pushes. For this a "listener" account will need to be subscribed to the corresponding bzr trees on launchpad, just like Buildbot is.
• To add a comment to a Jira issue one can use Jira REST API.
