Added 3 way F1 handover test with data exchange in the F1 pipeline.
The major change is that the UE is acting as a server in the handover
scenarion, so it needs to comply with the changes in !3280.

* 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).
address sanitizer fails with this error upon starting the DU:

SUMMARY: AddressSanitizer: odr-violation: global 'log_mem_write_side' at /oai-ran/common/utils/LOG/log.c:78:14
So we do as suggested and disable ODR violations to make the test pass.
A proper solution would be to link this function only once.
- Test only one DU at the CU (3 DUs is tested in F1+E1)
- Harmonize IP configuration to make it simpler to reuse in the F1+E1
test
- Speed up the test by reducing the number of steps to deploy core/RAN
- Add traffic test
3GPP has the concept of a gNB-DU ID and a (separate) gNB ID (for gNB,
CU). This commit introduces the gNB-DU as a separate ID that has to be
set in the configuration file. It is necessary, as some entities, e.g.,
the e2 agent, need to signal both IDs, e.g., to reconcile a CU and
(multiple) DU(s) belonging together.
* Proxy no longer required for git cloning
* Most of the IP addresses have been changed
- Remaining --> 192.168.18.89 for amariue
