* Changes rollback behaviour to apply soft deletes by default
Summary:
Addresses feature request: Flag in delete command to only delete aspects touched by an ingestion run; add flag to nuke everything by modifying the default behaviour of a rollback operation which will not by default delete an entity if a keyAspect is being rolled-back.
Instead the key aspect is kept and a StatusAspect is upserted with removed=true, effectively making a soft delete.
Another PR will follow to perform garbage collection on these soft deleted entities.
To keep old behaviour, a new parameter to the cli ingest rollback endpoint: --hard-delete was added.
