Pavel Hrdina 3ff35898a4 refactor detection of guest type capabilities
Each guest type can have its own capabilities and we should always ask
only for those capabilities.

The old approach was to get capabilities from libvirt and then for
example cycle trough all guests and return True, if any guest type
supports kvm or pae, etc.

Now we check those capabilities only for the correct guest type
according to defaults and input from user.
