Change in osmo-ttcn3-hacks[master]: upf: test Session Mod, test Network Instance

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/30929 ) Change subject: upf: test Session Mod, test Network Instance ...................................................................... upf: test Session Mod, test Network Instance Add tests and enhance the upf test suite to be closer to real world usage: - properly verify the F-TEIDs chosen by osmo-upf. - add tests with two-step session creation, i.e. with a Session Establishment followed by Session Modification indicating the remote F-TEID to use on the core side, as is the usual case. - Add module parameters for network instances to use in the test; dynamically configure osmo-upf's "netinst" config via VTY. - pass Network Instance in Create PDR, verify that osmo-upf returns the matching GTP IP addresses in Created PDR.
