We no longer use YAML in Ganeti at all. This patch converts the QA
configuration from YAML to JSON. JSON doesn't support comments and
I had to use a hack with fields starting with '#'.

This patch adds QA tests for most of the possible parameters in the
instance modify operation (exception being the MAC), and modifies the
sample QA file to run this test.

response ("... please give at least one parameter") as opposed to a
traceback.
