Looks good. Only a few comments on the reusability of the HO test mainly

PS6, Line 284:     def _get_counter_handover_success(self):
very clever, I like this idea and already have a few more counters ;-)

can be left to false until we finish HO  in the eNB

can you think of a way to somehow parameterize that test?  we already have the iperf time, that's one thing, but more comes below ..

we iterate once through the list ..

PS6, Line 47:     if num_handovers != 2:
and check here for exactly 2 HO. The reason I am asking is because we sometime want to run a HO test for 10 minutes and sometimes for 24h. For 24h we would expect >4000 HO perhaps. But the test is essentially the same so it would make sense to parameterize the runtime and pass/fail check.
