VOL-582: Update the Voltha core to support either consul or etcd in a kubernetes cluster

This is an initial commit for etcd support by voltha.

Although this code works on a single-node or on a kubernetes cluster, it is NOT ready
for prime time. The integration tests have yet to be written and a kubernetes install
is not yet available.
