make gsup ipa name configurable in osmo-sgsn.cfg
Add a 'gsup ipa-name' VTY command which overrides the default
IPA name used by the SGSN on the GSUP link towards the HLR.
This is required for GSUP routing in multi-SGSN networks.
The 'gsup ipa-name' option can only be set via the config file
because changing the IPA name at run-time conflicts with active
GSUP connections and routes configured in the HLR. The osmo-sgsn
program must be restarted if its IPA name needs to change.
