Use the cluster end point to compare le TL of différent nodes.

This might be useless for patroni versions > 3.0.4 (see #50)

In cluster_has_replica we now have (since #62):

A healthy replica:

has a replica or sync_standby role
has the same timeline as the leader and
- is in running state (patroni < V3.0.4)
- is in streaming or in archive recovery state (patroni >= V3.0.4)
has a lag lower or equal to max_lag
