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 Signed-off-by: Scott Murray <scott.murray@konsulko.com> Change-Id: I5ded74cfbd6987cd045b7b142fd9f38971aaef66
