Used tooz distribued lock mechanism for synchronizing various vnf instance tasks like instantiate, terminate and heal. It supports various backends, such as etcd, mysql, file locks, redis, zookeeper, etc. This change imports the "coordination" module, which is shared by Cinder, Manila and a few other projects. The lock backend can be selected using the CONF.coordination.backend_url config option. Change-Id: Ia4979571e788ecc4874ae0b62533fbc5277253a8 Blueprint: support-etsi-nfv-specs
