gprs_ns2: add signalling & data weights for UDP binds

Allow to assign a signalling and data weight to UDP binds.
Those weights will be used when doing dynamic configuration over
IP-SNS.
This is only the first part which only uses the assigned weights
when doing a new SNS configuration.
The outgoing change weight procedure will be supported in a later patch
when the SNS fsm supports outgoing procedures.
