Is the auto provisioning (subscriber-create-on-demand) of OSMO-NITB is still present or available in OSMO-BSC/OSMO-MSC/OSMO-HLR version?
No, it is not. As the feature is only relevant to quite non-standard use cases, it has not been a priority. See http://osmocom.org/issues/2542
In general, operating a network without your own SIM cards is highly discouraged in just about any environment. You cannot authenticate the subscriber, threfore you're vulnerable to all kinds of spoofing, impersonation attacks and fraud.
Also, you never know where such cards with IMSIs from third party operators will try to register. they might get rejected with "illegal sim card" from another operator, resulting in extremely unreliable and dissatisfactory user experience.
