test: nat44det - add session number check

- some tests need to reduce rate for ramp-up phase
- some tests need to extend trail duration in ramp-up phase
- removed 2n1l-10ge2p1x710-ethip4udp-nat44det-h1-p63-s63 suite
  as nat out ports are randomly selected from available port range
  so T-Rex stateless is not able to provide required out2in traffic
