Subject: [PATCH] ignore ethtool failures, other gate improvements

Gate enhancements:

1. On certain opendev hardware, it's not possible to change
   ethtool tunables, or the expected tunables are unavailable.
   Until we have a mechanism to schedule to the right hardware,
   we will issue a warning whenever these tests fail instead of
   failing the gate.
2. Add a check so that gate script will not run until there are
   no other instances of the gate script running on the same node,
   as this can cause spurious gate failures.
3. Print gate script tracebacks in the event of gate script faliure
4. Increase check interval for two exec tests that were seen to fail
   on one ocassion due to insufficient wait time.
