RMB32 implements only the tenant interface 2.0 and can only support that version at a time.
We will add "200 OK" or "204 No content" as a possible response for the v2 tenant.raml in the shared raml and update RMB accordingly. This requires no changes to RMB except an update to the "raml" project.
An RMB based module can, thus, implement postTenant and return the response synchronously. Okapi already allows sync responses and assumes that if no Location is returned, the module has fully performed the tenant init upon completion.
