A fix and a clean up to ktest, as well as two small features.

A way to allow users to skip a manual bisect.
  Allowing cherry picked patches to be tested.
 
 The cherry pick worked for a test I needed, but stressing it may
 not have all the desired effects. It doesn't cause any regressions
 so I kept it in.
