Change subject: [master][consensus] Procedure for copying system catalog

[master][consensus] Procedure for copying system catalog
This change outlines procedure to copy system catalog for the newlyadded
master using existing CLI tools and the master ChangeConfig RPC.
- Flag --consensus_allow_status_msg_for_failed_peer must be turned on
for existing masters.
- Start the new master with
--master_address_add_new_master=<new-master-hostport> and
--master_addresses that contains itself and existing masters.
- Invoke ChangeConfig to add the master.
- If the new master is promoted to being a VOTER then following tablet
copy steps can be skipped.
- Shutdown the new master.
- Delete the system catalog on the new master.
- Copy the system catalog from the leader master to the new master.
- Bring up the new master.
- Verify the new master is promoted as VOTER.
Bulk of the change is in the test code and involves refactoring to use
common parts of the earlier postive test case.
One functional change is in Raft consensus and adds the ability for the
leader to send status only messages to the peer even if it's in
FAILED_UNRECOVERABLE state. Without this change when the system catalog
is copied externally the new master remains in FAILED_UNRECOVERABLE
state and doesn't get promoted to being a VOTER despite the system
catalog being up to date. This behavior is currently disabled by default
and hidden under the --consensus_allow_status_msg_for_failed_peer flag.
