Refactor Cluster object
...
`Cluster.leader` is not reference to `Member` anymore, but to `Leader`
`Leader` class contains field `index` (update index). This field is very
useful for watching for events which changing leader key. Also `Leader`
contains `member` field, which should reference real member.

Be more robust on callbacks when cluster is down.
...
For 'on_stop' or 'on_restart' callbacks we cannot
call is_leader, because the cluster would be stopped.
Instead, call is_leader before running a callback.
In addition, make the call_nowait more robust by handling
the exceptions related to the DB cluster unavailability.

pg_is_in_recovery() = false and if it is there - remove it.

pg_basebackup) and if it is there - also remove it.
