Use node FQDN for nova-restore-compute-id

Hypervisor list for Nova get's populated with node FQDNs, which might
be completely different then nodename.

This is also reproducible in AIO, where ansible_facts['nodename'] is
`aio1`, while ansible_facts['fqdn'] is `aio1.openstack.local`.
And the fqdn is defined in hypervisor listing.

Since there could be a confusion in hostname/nodename/fqdn from
deployment to deployment, we make the fact variable configurable.
