config-daemon: Improve logging of draining state

[zeeke]

Executions of nodeUpdateHandler are not tracked by logs,
that make debugging problems harder.

Also, adding a log line to write the node name the config-daemon is working on.

Note: part of this work will be superseded by

• Drain controller #488

but it's still useful to deal with draining issue while waiting for that PR.
