[Starlingx-discuss] [Build] Debranding

We need a thread for the discussion of Debranding.  Interested parties should reply here. Intent is the removal of references to cgcs, tis, Titanium, stx-r1 and pike from the code base and it's supporting build systems.  Some of work will impact the CENGN build service, and might impact automated test resources as well. We'll need to progress slowly and carefully, and have backward compatibility kept in mind for the near term.
