I'd really like to see focus cross project. I don't want Ceilometer to
depend on Zoo Keeper, Cinder to depend on etcd, etc. This is not ideal
for an operator to have to deploy, learn and maintain each of these
solutions.

I think this is difficult when you consider everyone wants options of
their preferred DLM. If we went this route, we should pick one.

Regardless, I want to know if we really need a DLM. Does Ceilometer
really need a DLM? Does Cinder really need a DLM? Can we just use a
hash ring solution where operators don't even have to know or care
about deploying a DLM and running multiple instances of Cinder manager
just works?
