Fix post-config of OVS for manila-share servers

A host that is in the manila-share group, but not in controllers
network, etc., will fail service deployment if it is not using the
generic manila driver (eg, if it is using the CephFS native driver).
This is because deployment of openvswitch-vswitchd is predicated on
the drivers enabled for manila-share.  However, this predicate is not
universally applied.  Where inventory group membership is used the
dependency on openvswitch-vswitchd presence will fail.
