[Nut-upsuser] On retiring some terminology

Thu Apr 1 12:00:27 BST 2021

Hello all,

  As some people watching GitHub closely might have noticed, the majority
of proposed changes (for primary/secondary in the end) were merged around
weekend. This impacts text documentation and keyword support for upsmon
configuration, testing welcome :)

  Some work remains for image files in documentation, and the protocol/ABI
were not touched so far.

  Following the recent eminent emergence of Religiously Correct Speech
zealots, while at this, we like other projects should also contemplate
supporting as aliases or even primary key words a dichotomy of a "shepherd"
and (some) "sheep" in this context, that might make intuitive sense.

Happy holidays and thanks for voting,
Jim Klimov
