• remove no longer used ru/lopcomm/supervision.jinja2.py
• restore removed + keep on touching RU watchdog comment. Now it relates to ru/lopcomm/stats which became responsible for this function.
• move code of RU-netconf-connection promise to be located nearby stats service because this promise interacts with that service, and grouping code by interaction makes it easier to understand for humans. Previously RU-netconf-connection was interacting with supervision service whish is gone after the patch in question.
• use double vertical space to delimit logical sections from each other.

open questions:

• before the patch in question stats code was reconnecting after each error with 10 seconds pause. Now it logs it wants to reconnect but does not because top-level while True was removed. Was that intended?

  If it was not the intent then new stats code will fail after any single error and won't reconnect to RU by itself.
