When new simple configuration is replicated after leaving joint consensus we still may send a request to follower that is going to be removed after the transition from joint to simple state. This way there is a chance that the follower will receive an information about it being removed from the cluster. The change introduced here is just an optimization and it does not influence correctness or configuration change semantics. It just allows the removed follower to discover its removal. The last configuration change delivery isn't guaranteed and it may happen that the follower will not receive it so we should not treat it as reliable mechanism to discover removal.

Added a piece of logic that doesn't allow decommissioned node to rejoin the cluster after it is restarted. This way a node that was decommissioned will always require a data wipe to be able to join the cluster again. It will make restarting decommissioned safe.

…arts When Redpanda is started it may be the case that it will not be able to join the cluster but its process can still be up and running. To test this behavior we may need to start Redpanda without waiting for it to be fully operational. Signed-off-by: Michal Maslanka <michal@redpanda.com> (cherry picked from commit a5a1b83)
