Make sure patroni is not using stale connections.
...
After the PostgreSQL crash (i.e. with kill -9), the backend
patroni connects to may still exist. In this case, patroni
will get stale postgres role from this backend, preventing
a restarted node with a leader lock from being promoted.
Easily reproducible and also observed in a staging environment
after the postgres crash due to out of disk space.

Feature/pg rewind unclean shutdown. Allow pg_rewind to rewind the former master if it was uncleanly shutdown or just lost the connection and advanced past the point where the new master had promoted.

Address the code review by Alex Kukushkin:
...
- check the link before checking the file when deciding to remove it,
as isfile follows symlinks and, therefore, may return True on them.
- Remove append mode from write_pgpass, as it is always written anew
before it is used.
- make pg_controldata return an empty hash in case of an error, and
check for the empty value return by this function before using it.
some other minior fixed and test updates.

Call pg_rewind in case of the master's unclean shutdown.
...
If patroni detects the former master was killed, it runs
it first in a single-user mode and then shuts down normally,
to make sure pg_rewind will see a normal shut down status
in pg_controldata.
Add a flag need_rewind, since the point where it is detected
that rewind might be necessary is moved out the code that
runs rewind.
