  - Merge "Improve ping test coverage during update."
  - Improve ping test coverage during update.
    
    The ping test starts at the beginning of the "update run" phase and
    stops after it finishes. This means after all roles has been updated.
    
    With this patch we stop, test and restart the ping in-between each
    role update.
    
    This means:
    
     1. that we detect error earlier;
     2. we detect error related to new flow being created during update
        run;
    
    The point 2. was discovered to be an important test as ovn can have
    existing flow still working, but new flow breaking. With this new
    behavior for the ping test we catch such error.
    
    The downside is that we have even more sensible to any % based testing
    as the same number of error will give you an higher percentage as we
    spend less time in the test for each run. This could be seen as
    another improvement.
    
    We're splitting the ping test into two stages so that if the ping
    fails to start (as it would be for this particular issue) we would
    detect it immediately instead of waiting for the end of the run.
    
    When we doing batch update (all roles in parallel) we deactivate that
    mechanism and fall back to the previous one as there is no in-between
    role step there.
    
    We also prevent the stop ping from searching into all home
    subdirectory as I had an issue in local testing where one subdirectory
    had unreadable files (after a local podman run). This shouldn't happen
    in CI, but is good to have for local testing.
