ci/lava: Filter log lines from LAVA return

Start to differentiate between the different types of LAVA log message;
the only visible change right now is that we make warnings and errors
bold and red to match bare-metal, but it comes in useful later as we
will use the results markers to watch us step through the different
stages of job execution.
