Service Models support in CU-UP 

  - e2_ran_func library divided into e2_ran_func_cuup (CU-UP only) and e2_ran_func_du_cucp_cuup (DU, CU, CU-CP and gNB-mono)
  - GTP SM is not yet implemented in CU-UP -> CU-UP doesn't store PDU session information
  - PDCP SM support for gNB-mono, CU and CU-UP
  - KPM SM support for all node types (DU, CU, CU-UP, CU-CP and gNB-mono)
