feat(soak): add warmup and stats
Specifically on 2n-icx, soak tests are suffering
from the first search trial (at half of max rate)
reporting unsent packets, thus polluting the results, see CSIT-1867.
This adds a plain trial (no stats, result ignored), fixing the issue.
To keep the structure similar to NDRPDR tests,
stats trial is done after the search, at the discovered critical rate.
Ticket: CSIT-1867
