Current Requirement: The VNF MUST support Integration functionality via API/Syslog/SNMP to other functional modules in the network (e.g., PCRF, PCEF) that enable dynamic security control by blocking the malicious traffic or malicious end users.

Proposal: Remove requirement because it is redundant with R-821839

Proposed Requirement: The VNF MUST support Integration functionality via API/Syslog/SNMP to other functional modules in the network (e.g., PCRF, PCEF, PCF) that enable dynamic security control by blocking the malicious traffic or malicious end users.

Reason: Added PCF to the example of functional modules because PCRF and PCEF are for 4G and PCF is for 5G
