Bugfix in has_lock: sometimes leader can be undefined

Bugfix. It wasn't possible to start the old cluster if all its members were shutdown.
...
Basically this is rollback to the original decision tree with the small exception:
1 - If leader is defined and it's not me - then slave would be started immidiately
with the correct recovery conf.
2 - If leader is defined in and it's my host, then it will start instance in
readonly (but without primary_conninfo in recovery.conf)
3 - And the third case - if the leader is not defined - it also will start
instance in readonly, without primary_conninfo.
After performing 2 or 3 it will perform usual decision tree.

Start slave with the correct recovery.conf on governor start
...
Also governor is able to pick up already running master and slave
instances without restarting them.
In case is you have a lock and postgres is not running behaviour remains
the same: it will start master in read only mode and then promote if it
still has the lock.

dempote and follow_the_leader have the same functionality

Now methods supporting the case when leader is not defined. There would
be no primary_conninfo in recovery.conf. I like it more comparing to
