Fixes test_metrics test

Ceilometer API was removed in Queens, meaning that test_metrics has
not way to validate the metrics collected by the ceilometer-polling
agent.

The metrics are instead sent and collected by Gnocchi.

This patch adds a Gnocchi client, and updates the test_metrics
to use this client properly.
