etcd_docker 4: Incorporate docker based etcd into Go integration tests (

#4148) (#4206)

PR 4 for #4144

High level approach is as described in #4144 .

This PR integrates docker based etcd into our Go integration tests. It removes the need to have the embed package running
in m3db for them, but doesn't yet touch that functionality.
