Physical reservations don't work when service name != hypervisor_name

[Sylvain Bauza]

Due to FQDN troubles with Havana, sometimes service_name for compute doesn't match with hypervisor_hostname.
When an host is dedicated to Climate thanks to host-create, Nova puts the host in the freepool agg and take use of service_name.

But, when the lease is starting, when trying to move the host from the freepool to the user agg, it is not found as possibly the names are different.

Ideally, we should store service_name as well, and search from the service_name here (instead of hypervisor_hostname) :

    PR Plugin now uses service_name to identify hosts

    Now the Physical Resource plugin uses the service name instead of
    hypervisor host name. This is because in Havana (and could be
    a chance that happens in Icehouse), the host name of the compute node
    is not the same as the service name.
