Reorganise compute config reference
This patch
* Removes content that is covered by installation (adding group,
fixing file permissions, multiple compute nodes)
* Removes empty section (hypervisors)
* Merges duplicate content (overview/explanation of nova.conf)
* Flattens section structure, and removes "post-install config"
section label that was a legacy of previous structure
* Addresses outdated reference to Xen configuration info.
