From 82c1c0ab04219f9453f1b3a14a9754068e360583 Mon Sep 17 00:00:00 2001

Subject: Rework to switch to using KUKSA.val databroker

Rework to use the "VAL" gRPC API from the KUKSA.val databroker
instead of the older server's WebSocket interface.  Some source
files have been renamed to match the class naming to provide
a bit more consistency.

Bug-AGL: SPEC-4762
