deploy: Add ganeti-qa command

To install a minimal Ganeti cluster for QA run:

 snf-deploy ganeti-qa

This will create a ganeti cluster. The test instances will resolve on
the local nameserver. On the client node it clones the official repo
and installs all required packages required for ganeti development.
A sample qa json file is uploaded under /tmp.

To run the qa go to the client node and run:

 # cd ganeti
 # python ganeti-qa.py /tmp/qa-sample.json --yes-do-it

Note that the installed version in the qa cluster should be the same
used in the qa source.
