sms charging: Implement SMS online ECUR charging based on 3GPP TS 32.274
Event Charging with Unit Reservation (ECUR) principle is used for SMS online charging in osmo-nitb.
Osmo-nitb generates Reserve Units information which is transferred to OCS.
For this purpose, osmo-nitb utilizes the Reserve Units procedure that is specified in TS 32.274 and TS 32.299.
The Reserve Units procedure employs the Reserve Units Request and Reserve Units Response messages.
