 2ea0357854 DCS failsafe mode (#2379) 
If enabled it will allow Patroni to cope with DCS outages.
In case of a DCS outage the leader tries to call all remaining members in the cluster via API and if all of them respond with success the leader will not be demoted.

The failsafe_mode could be enabled by running
```sh
patronictl edit-config -s failsafe_mode=true
```

or by calling the `/config` REST API endpoint.
