gprs_ns2: rework IP-SNS binds
Introduce a `ip-sns-bind BINDID` vty command within a `nse` vty object.
The ip-sns-bind defines the binds which will be used by the dynamic
configuration with IP-SNS.
This is only the first part which only uses the binds when doing a
new SNS configuration.
The outgoing add procedure will be supported in a later patch
when the SNS fsm supports outgoing procedures.
This is a behaviour change of the API and must be synchronized with
the osmo-pcu. Otherwise SNS won't work with osmo-pcu.
