Opennebula aii

- removed some comments
- included post_reboot hook to install acpid
- removed hardcoded sleep time
- aii remove function bug fixes
none yet. it is in cpan, but not packaged (and i made serious modifications to it, so whatever is packaged is probably out of date and not usable here).
for now, we make our own packages with `cpan2rpm`. once both aii and the component are bit stable, we can enforce a minimal version.
we can update the README.md maybe with some explanation how to get/build the rpms?
