* it is now possible to specify a comma separated list of endpoints
* the documentation as been updated to explain that:
+ for node services if several addresses are specified they should
point to different interfaces on the same server.
+ for cluster services several addresses should be used because we
want the cluster status so the more API we try the better our chance
of having a reply.
The checks `cluster_config_has_changed` and `node_tl_has_changed` use a
state file to store the previous value of the config hash and the
timeline.
Previously the check would fail if something changed, but the new value
would be saved directly. This behavious has changed. The new value
is saved only if `--save` is passed to the check.
The mimics the way [check_pgactivity] manages this kind of checks.
