We need to all get together and figure out and understand what the issues with DLM are, what lock management features have been replicated by many various projects and what something like zab (zookeeper), raft (consul, etc.d, ...), paxos (?), or other variant can offer to openstack and its diverse set of projects.

Why: without understanding the problem, and what the solutions are, what the various offerings provide... we have no hope in fixing it, so let's work on that.
Expected result: understanding what a DLM is, what some of the common patterns they offer are, and in my happy world/vision agreeing that a DLM solution (ideally one, not many) will help openstack(s) future (in terms of long-term health, operability, features, and so-on); reduce common code that is replicated similar features and possibly bring world peace.
