The PR contains more code cleanups, mostly in gossiper. Dropping more gossiper state leaving only NORMAL and SHUTDOWN. All other states are checked against topology state. Those two are left because SHUTDOWN state is propagated through gossiper only and when the node is not in SHUTDOWN it should be in some other state.
No need to backport. Cleanups.
