Trigger jobs for stackforge/python-jenkins

The usual entry points pep8, py26 and py27 are provided by If58730d84.

Expand the python-jobs template with some tweaks:
- 'coverage' added to 'check' pipeline and made non voting
- 'docs' is commented out because setup.py does not have a build_sphinx
  entry point yet.
- adds python33 as a non voter since we want to eventually support 3.3.

James confirmed that openstackci got added to the pypi project. Added
release related triggers as well.  The postmirror jobs are not needed.
