benoit 78ef0f6ada Fix cluster_node_count's management of replication states
The service now supports the `streaming` state.

Since we dont check for lag or timeline in this service, a healthy node
is :

* leader : in a running state
* standby_leader : running (pre Patroni 3.0.4), streaming otherwise
* standby & sync_standby : running (pre Patroni 3.0.4), streaming otherwise

Updated the tests for this service.
