Cole Robinson f27e203732 cli: Skip MAC collision error with --check mac_in_use=
There's valid cases where a VM can be defined with a conflicting MAC
address. Prior to  ebd6091cc8e4 and related refactorings we were more
lax here if the conflicting VM wasn't running, but now we are blocking
some valid usage.

Hoist the validation check up to cli.py and add --check mac_in_use=off
to skip the validation. Advertise it like we do for other checks, so
now a collision error will look something like:

The MAC address '22:11:11:11:11:11' is in use by another virtual
machine. (Use --check mac_in_use=off or --check all=off to override)
