Allow sending of Administrator UIDs for *NETWORK_STACK

Browse Source 
This change allows callers with the NETWORK_STACK or
PERMISSION_NETWORK_STACK to receive administrator UIDs. This will be
used by the VCN to ensure that administrator UIDs are accurately
populated, ensuring that the ConnectivityDiagnostics are triggered for
the VCN.
