Low: ticket: refine log messages on not all acks received
Medium: doc: man page update
Low: ticket: log more information when broadcasting
Low: ticket: remove one log message

When not all acks get received, we actually get to do the logging
on the next cron due to timing. The warning at that time may just
confuse users, so better not to say anything. Add ticket name to
other messages.
Medium: raft: schedule next ticket processing after ticket expiry on followers
Low: ticket: log message when revoking ticket
Medium: ticket: allow revoke only on leaders

If a client request comes to another boothd, it will return with
redirect and it is up to the client to connect to another site.
Medium: raft: reduce the default timeout to 5 seconds
Dev: print expiry time in the debug msg
Dev: function rename
Medium: ticket: increment lease time only when majority held

We need to send a new lease time to others with the broadcast,
but cannot update our local copy until we reached majority.
Otherwise, we'd lose the ticket too late.

The ticket now gets updated with the new RPC which is broadcasted
after the majority was reached. Otherwise, on losing majority
which may have happened in the meantime, some followers may have
different (wrong) information about the ticket expiration time.
