Add Patroni failsafe_mode parameter (#2076)

Browse Source 
This commit adds support of a not-yet-released Patroni feature that allows postgres to run as primary in case of a failed leader lock update.
* Add Patroni 'failsafe_mode' local parameter (enable for a single PG cluster)
* Allow configuring Patroni 'failsafe_mode' parameter globally
