Convert DomainBase's contacts to VKeys (#574)

* Convert DomainBase's contacts to VKeys

Convert usage of DomainBase contacts from Key to VKey.  This is the same
change as done for nameserver hosts, as it affects all external interfaces.
As with nameserver hosts, we preserve the existing representation so as not to
afffect the datastore representation.
