eee9c4cf33 Fix two direct memory leaks of CU-UP tester
Direct leak of 100 byte(s) in 1 object(s) allocated from:

0348aa08b9 Remove rb_id parameter from SDAP TX entity - QFI determines DRB mapping
- Remove rb_id parameter from nr_sdap_tx_entity() function signature
- Update tx_entity function pointer
- Remove rb_id parameter from sdap_data_req() function signature
- Remove unused rb_id variable from sdap_tun_read_thread

The rb_id parameter was redundant since SDAP determines DRB ID
from QFI mapping via entity->qfi2drb_map(entity, qfi). This
simplifies the interface.

5d9db1688a Refactor port number out of newGtpuCreateTunnel()
The (remote) port number of the GTP module is configured during
initialization. It is therefore not required when calling
newGtpuCreateTunnel(), and could even lead to bugs (if another port
number is used than specified during GTP init).

07629e29d6 Add CU-UP load tester and documentation
This is a simple CU-UP load tester. It sets up a configurable number of UEs in the
CU-UP, then sends GTP traffic in downlink/uplink in the N3-F1/F1-N3
direction at the CU-UP. It then compares the sent and received data.

Additional parameters, such as amount of traffic, test length, packet
size, and IP addresses/ports are configurable.

To run:

    mkdir build && cd build && cmake .. -GNinja && ninja nr-cuup nr-cuup-load-test params_libconfig
    ./tests/nr-cuup/nr-cuup-load-test
    ./nr-cuup -O ../tests/nr-cuup/load-test.conf

The tester should be able to detect lost and reordered packets.

Example lost: Receive order 2,3,5,6 (lost packet 4)
=> on packet 2, expected 2, next=expected+1=3
=> on packet 3, expected 3, next=expected+1=4
=> on packet 5, expected 4, diff=5-4=1 (lost 1), next=payload+1=6
=> on packet 6, expected 6
=> 1 lost

Example reordered: Receiver order 2,5,3,6 (lost packet 4)
=> on packet 2, expected 2, next=expected+1=3
=> on packet 5, expected 3, diff=5-3=2 (lost 2), next=payload+1=6
=> on packet 3, expected 6, (reduce lost by 1 to 1), next=expected=6
=> on packet 6, expected 6
=> 1 lost

Example reordered: Receiver order 2,5,3,4,6 (no losses)
