Subject: [PATCH 2/9] fence_compute: Don't list hypervisors but nova-compute
 services

Everything we do (evacuate, force_down) is on nova-compute services, so
there's no reason to list hypervisors; just directly look for
nova-compute services.

This matters as hypervisors are always FQDN, while nova service hosts
can be short hostnames.
