Show HTTPInternalServerError for the metaquery not implemented

[Haomeng,Wang]

I think for the "metaquery not implemented" we dont support, should not return "HTTPInternalServerError (HTTP 500)" error message for user from command line call, but we can find the actual result in the API log.

[root@osee26-control01 ~]# ceilometer meter-list -q metadata.instance_type=1
No handlers could be found for logger "ceilometerclient.common.http"
HTTPInternalServerError (HTTP 500)

NotImplementedError: metaquery not implemented

@Mehdi Abaakouk, I just find a bp which implement the SQL metadata query function, so this defect should be invalid once the bp code change is merged - https://review.openstack.org/#/c/49456/

[Mehdi Abaakouk (sileht)]

They are many other ceilometer parts that have NotImplmenetedError and the API should return 501 intead of 500.

For example some other BD backends have limited feature: http://docs.openstack.org/developer/ceilometer/install/dbreco.html

marking invalid since all backends support metaquery
