[Tarantool-patches] [PATCH 1/3] [tosquash] raft: vote without a new term when possible

[Vladislav Shpilevoy <v.shpilevoy@tarantool.org>]

When instance wrote something to WAL and saw that there is no a
leader, and no vote, it started new term + wrote a vote for self.
Really the new term wasn't necessary. Since the node didn't vote
in the current term yet, it can vote right away.

It is not about saving term numbers. More about making the logs
more understandable. Otherwise it looks strange, that in some
terms a node didn't participate at all and just skipped them even
though it started tehm.
