oVirt/RHEV-M module

I created a module to control the oVirt/RHEV API.
I also (just) noticed there was another ansible module already that did this, but it also lacks some featured I need very much. 
Most explicit, multi disk and multi nic environments.
This also gives the option to control your bootoptions and HA & memory reservation

I have compared it a bit, and it looks like a complete rewrite, but with some more functionality.
The other reason I made it as a new module is that if I would add these features, it would break the old one.
Especially since the disks and nics use complex arguments
