[S] Change in upf-benchmark[master]: osmo-upf-load-gen: Add vty cmd to skip binding local GTPU ports

pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/upf-benchmark/+/39421?usp=email ) Change subject: osmo-upf-load-gen: Add vty cmd to skip binding local GTPU ports ...................................................................... osmo-upf-load-gen: Add vty cmd to skip binding local GTPU ports This is useful when osmo-upf-load-gen is used only to generate the PFCP sessions acting solely as SMF.
