    Removed the host FQDN from the exception message

    Deletion of an instance after disabling the hypervisor by a non-admin
     user leaks the host fqdn in fault msg of instance.Removing the
    'host' field from the error message of HypervisorUnavaiable
    cause it's leaking host fqdn to non-admin users. The admin user will
    see the Hypervisor unavailable exception msg but will be able to figure
    on which compute host the guest is on and that the connection is broken.
