patch-test triggers to run csit on patches

Sam Hague <shague@...>

All the projects in the to: list have the ability to run genius and netvirt csit on any patch using a gerrit comment. The job is non-voting and only reports back status. If you do run the csit and notice a non-success, please ping the genius and netvirt lists to look at the job so the team can fix any issues found.

The format of the comment is: test-<project>-<genius|netvirt|cluster-netvirt>. 

For example, on a controller patch, you would add this comment to run genius csit: test-controller-genius. This is shown in controller patch:

For aaa to run netvirt csit, test-aaa-netvirt.

Thanks, Sam
