After the openstack application is removed, stale hypervisor information
in the VIM's database could cause repeated controller host swacts when a
worker host lock/unlock is attempted. Qualifying the hypervisor query
with an enabled compute plugin will resolve this. Note that subsequent
openstack application apply will re-initialize the VIM's hypervisor
information in the database.
