Add a GPRS test that uses more than one subscriber, if possible even more.

Blocked since we don't have more than 1 EC20 currently connected to osmo-gsm-tester (SYS#4381). Once we have it, I can start working on related tests. I'll do test which tests running several iperf3 sessions concurrently, 1 per MS.

For test case regarding CS<->PS, see #2204. Similar stuff is already implemented for dynamic timeslots in "dynts" suite.

I tested with 2 MS in RnD (there's only 2 EC20 there) and everything looks fine, speed looks similar for both too:
