Add test to trigger re-establishment to RFSIM F1 CI

Browse Source 
* trigger re-establshemnt on DU: reset RLC counters on DRB 1
  for OAI UE, since SRB 1 does not work for lack of periodic
  measurements reports
* how is the re-establishment triggered?
  * a transmission on DRB 1 occurs
  * detection of a mismatch of RLC counters at the UE side
  * max number of RLC retransmissions reached
  * RLF detection
* verify re-establishment on CU: we ping the core from the UE; this
  sends packets on DRB, and because the sequence number mismatches, will
  trigger a reestablishment. We accept in the ping that a couple of
  packets might be lost; after ping is over, reestablishment must be
  done as well (else the ping will already fail).
