Refactor SystemIPs Field in API to Support MAC Addresses

[hardikdr]

What would you like to be added:
Refactor the SystemIPs field in the API to a more generic name like SystemIDs that can accommodate both IP addresses and MAC addresses. Alternatively, consider adding a separate MACAddress field to the API to handle environments where MAC addresses are needed alongside IP addresses.

Why is this needed: This change would allow for more versatile client identification and management, supporting a broader range of network configurations and deployment scenarios.
