m/n/core/cluster: migrate to events and etcd namespaced client

This moves the status of the cluster manager to use a local event
variable. Watchers (like the node startup code) can now use this to get
updates on the state of the node and its cluster membership in a way
that's more abstracted from a sequential startup. This will permit us to
move a lof othe startup code into code common across different node
lifecycle paths.

Test Plan: Refactor, exercised by e2e.
