[VOL-1997] Remove transaction timeout for a non-active rw_core

This commit cleans up the transaction processing between two
cores in a pair.  It prevents the core not processing the request
to grab the request based on a timeout only.

Since this update heavily relies on the etcd mechanism then customized
local tests (not unit as could not find a full-featured etcd mock)
were run against it as well as some basic manual tests with
kind-voltha.

There is a TODO item in this commit to implement a peer-probe
mechanism to guarantee that a core in a pair has actually died
before a switch over is done.

Minor updates after first review.
