[PFCP] SGWU/UPF Restoration (#2223) 
TS23.007 17.4.1
19A PFCP based restart procedures

After a PFCP entity has restarted, it shall immediately update all local Recovery Time Stamps and shall clear all remote
Recovery Time Stamps. When peer PFCP entities information is available, i.e. when the PFCP Association is still alive,
the restarted PFCP entity shall send its updated Recovery Time Stamps in a Heartbeat Request message to the peer
PFCP entities before initiating any PFCP session signalling.

o Generate the private key as below.
   $ openssl genpkey -algorithm X25519 -out /etc/open5gs/hnet/curve25519-1.key
   $ openssl ecparam -name prime256v1 -genkey -conv_form compressed -out /etc/open5gs/hnet/secp256r1-2.key

 o The private and public keys can be viewed with the command.
   The public key is used when creating the SIM.
   $ openssl pkey -in /etc/open5gs/hnet/curve25519-1.key -text
   $ openssl ec -in /etc/open5gs/hnet/secp256r1-2.key -conv_form compressed -text

Sukchan Lee 1bed0d5872 [#568] Add GTP-U Error Indication Handling 
So far, no operation was performed when Error Indication was received
from eNodeB. For that reason, I solved #568 issues by controlling
the MME to prevent this from happening.

Now, when GTP-U Error Indication is received, MME and SGW are implemented
to do what they have to do. I hope that the network can be restored
by responding appropriately even if Error Indication occurs.
