Enhancements to docimpact bug creation code

NB: This has not been tested yet, as launchpad staging server is down.

These changes:
* adds the gerrit review URL to the top of created bugs
(so bug assignees/triagers can look at the patch easily)

* set the tag of the bug to be the project/repo name, as is the
docs triaging standard
