Bostjan Meglic 7e6568d800 [SMF] Send PDU Session Establish Accept to serving AMF
In case there are multiple AMF registered to NRF, SMF would pick only
the first AMF from the list.
In the case of sending PDU Session Establishment Accept from SMF to
AMF, this would mean a high chance of failure since the AMF might
be different than the original requester, and would not know about a
particular UE.

Modify SMF to use ServingNfId field from original request
SmContextCreateData from AMF to determine to which AMF should it send
PDU Session Establishment Accept message.

Sukchan Lee c6c8dc1256 [PFCP] Support Multi-CP with One-UP
A problem occurred when there was one SGWU/UPF and multiple SGWC/SMF.

When SGWU and UPF create a session, if the SEID is the same,
the existing session information is used without creating an additional session.

These problems were solved by using the F-SEID including IP information
in the process of checking the existing session.

Sukchan Lee e0a487f479 [SMF] Optimiza Session Modification Message
For video in VoNR, multiple QosFlow is required in one session.

In the past, since only one Session Modification Message was supported,
QoS-Flow was put into several Session Messages one by one and processed.

Now that multiple QoS-Flows can be supported,
it is optimized to process one session modification message.
