Acceptance criteria

• Default config uses the shippped nats for registry / cache / stores
• The startup process is "graceful enough" to accept that the NATS service need some startup time.

Cache and store switch missing? @micbar @kobergj

Should we close then? Seems like all acceptance criteria are fulfilled of this ticket
