Remove subtypes of wasGeneratedBy

[glguy]

These subtypes are not offering a semantic refinement and are being used as aliases for the underlying wasGeneratedBy relationship that should be used in place of these aliases.

I added this PR to Pre-Release 9 so we don't lose track of it if we want to get it into the next release.

GramaTech uses http://arcos.rack/TESTING#producedBy, SRI uses http://arcos.rack/SYSTEM#producedBy

I think this change is worth doing, but we'll want these teams to update their ingestion process not to use the subrelations.

@cuddihyge, can you please regenerate the nodegroups to reflect these changes? At minimum, ingestion/arcos.rack and probably ingestion/arcos.turnstile.

@tuxji John, are these being generated automatically during the CI yet, or should we still build them manually and check them in.
(this is the IngestTemplateGenerator step that builds CDR's)

[tuxji]

Not yet. I will start making the changes needed to generate the nodegroups automatically.
