Not needed anymore as we now use IPROTO_REQUEST_STATUS instead of
IPROTO_REQUEST_VOTE. Let's remove it altogether and reuse its code
for IPROTO_STATUS (they are never decoded together so no conflict
should happen). Worst that can happen is we choose a read-only master
when bootstrapping an older version of tarantool.
