Ceilometer can't find nova instance due to host name mismatch

[Pradeep Kilambi]

Ceilometer can't find nova instance because of name differences: it appears as compute-2 for ceilometer in ceilometer.conf (host = socket.gethostname()) and as
host=compute-2.localdomain in nova.conf.
So there are no events sent from that instance.

There are several ways of workaround, from removing host= in
nova.conf to adding it to ceilometer.conf.It should work by default so there should not be any need to add or remove host.

    Set host name explicitly for telemetry

    Without this there could be a mismatch with other services like
    nova and neutron and ceilometer wont find nova instances.
