Add configurable automatic group up/down feature based on node availability
Available under content cluster tuning tag; feature is currently disabled by
default (need prod experience for this first).
Also improves handling of nodes removed from config by ensuring these are
taken out of the core working cluster state instead of just patched away
before each state publish.
