Domain not found

when vm1 live migrate from host1 to host2, ceilometer.compute.discovery.InstanceDiscovery still hold the vm1 in self.instances, thus causing Exception.

For example, when poll disk.read.bytes, the exception is:
2017-01-13 11:14:40.258 30189 DEBUG ceilometer.compute.pollsters.disk [req-e3cee3af-42c9-4d37-aa41-b39906fbbd04 admin - - - -] Exception while getting samples Error from libvirt while looking up instance <name=instance-000001eb, id=d90dd5e7-25d0-4ff6-b8e1-337e297147b0>: [Error Code 42] Domain not found: no domain with matching uuid 'd90dd5e7-25d0-4ff6-b8e1-337e297147b0' get_samples /usr/lib/python2.7/site-packages/ceilometer/compute/pollsters/disk.py:161

Need add a method to remove vm1 from self.instances.

this is related to bug 1594285. i should mention in ocata we don't use this cache anymore (not by default if using libvirt)

    Add support of refereshing the resource info in local cache

    The local resource caching mechanism may cause legacy resource info
    resided in the local cache and never be cleaned, uless the service
    being restarted. e.g. an instance has been migrated to another host, the
    instance info will reside in the cache on the ceilometer-polling
    service running on the old compute host.
