If an SGSN in a pool is down we expect the messages to instead be sent
to a different SGSN in the pool. That SGSN will not necessarily know
what to do with those messages, but it should )implicitly) detach that
UE so that it can reattach at the new SGSN. Otherwise UEs on a failed
SGSN would simply stop working as the messages would never be forwarded
anywhere.
This test also adjusts the NS timers so the failed NSVCs are detected
faster.

In libosmocore I34b8fde2955ecc010d1dcd9512e1bba9211e2c0d we introduced
a new log subsystem; enabel it in the related configs here

This reflects the more realistic use cases: IP-SNS is used on the BSS
side, where osmo-gbproxy then behaves in SGSN role.

With libosmocore commit the SNS configuration requires a ip-sns-bind vty configuration
to define the binds which should be use.

We change the osmo-gbproxy.cfg to use NRI 3 for SGSN-0 (NSEI 101) and
NRI 4 for SGSN-1 (NSEI 102).
We also add the capability to GBProxy_Tests to allocate P-TMSI with
a specific NRI and default to the first NRI of SGSN-0 so all tests
written still for a single-SGSN-non-pool scenario pass without any
modification.

This adds the required code changes and minimal configuration to both
osmo-gbproxy.cfg and GBProxy_Tests to have osmo-gbproxy connect to two
SGSNs.
No NRI mappings are configured and hence the second SGSN isn't really
used for anything except for bringing the NS-VCs and BVCs up.

The first testcase, TC_BVC_bringup just waits for NS/BSSGP Emulation to
do their thing. If nothing fails there then we pass.
