[AWARE] Fix Latency/DataPathStress NDP OOB tests

The above tests would only work for every other NDP setup. The
issue is (most likely) connectivity manager keeping a request
around after it is terminated to see whether other factories
will resolve it. Solution is:

Long term: immediate failure b/31402907
Short term:
- Add delay between iterations (this CL)
- Change the network request, can only be done for passphrase/pmk
  NDPs, not for open ones (which is this test)

Bug: 31940045
Test: tests passing
