Didn't we agree that PROMOTE should bump the term always? I see no purpose
for the PROMOTE which never bumps the term except for the tests, but for
such occasion it would be better to have internal.make_leader() or something
which bypasses everything. Although the best option would to bump the term
always.
I see you did something in the last commit about that, but the part
about `limbo->promote_greatest_term > 1` still remains. It looks very
illegal to point out some terms as "special".
