In Tokyo, there was a cross project session on distributed key locking: https://etherpad.openstack.org/p/mitaka-cross-project-dlm In support of the discussion there, we'll need support for a zookeeper service in Devstack and ability to use libraries like Tooz for DLM functionality. In this review, we pick up some configuration files from monasca-api and copy the lib/template to implement the zookeeper lifecycle. Those services that need zookeeper need to add "zookeeper" in ENABLED_SERVICES. Change-Id: Icef26e5cdaa930a581e27d330e47706776a7f98f

# To avoid seeks ZooKeeper allocates space in the transaction log file in

# blocks of preAllocSize kilobytes. The default block size is 64M. One reason

# there is no more than globalOutstandingLimit outstanding requests in the

# system. The default limit is 1,000.ZooKeeper logs transactions to a
