[Users] Fence-virt support

[Sander Grendelman]

It "kind of" worked.

I did an insert into the database to add an "xvm" fence mode.
After that I had to first change the mode to ipmilan to get
rid of a couple of mandatory fields. The setup also breaks
when I try to edit a host.

The fence mechanism makes a couple of assumptions that
don't work with fence-virtd:

- fence-virtd uses a keyfile, no username and password.
- fence-virtd uses port=vmname to identify a VM

The gui has mandatory username and password fields and
the standard port/sshport field only takes numeric values.

Some of the problems I ran into are probably related to
