quoting breaks for non ascii characters in utils.py

      monitord is tripping over the quoting function it uses to quote the stdout section in the kickstart output. Gideon can you take a look?

      Recently I have been noticing that when running a number of my
      workflows pegasus-analyser starts reporting incorrect information
      after some amount of time. This has the knock-on effect that
      pegasus-plots and the dashboard also report incorrect information.
      This generally has the effect that analyser reports my job is only
      (say) 10% complete, when really it is much further along.

      Two examples of this on sugar-dev3:


      One recommendation from pegasus-plots was to run pegasus-monitord in
      replay mode. So I tried this:

      pegasus-monitord --verbose --replay

      After about 10 minutes that command failed with:

      KeyError: u'\xe2'

      The only strange thing I notice about the listed .out file is that it
      contains some warning messages from scipy compiling a function. These
      messages contain non-ASCII characters:

      warning: unused variable ‘Narr’

      (specifically the quotes around Narr).

      Is it obvious what the problem is here? Is there anything I can do to
      fix it? The workflows in question are being used to profile different
      stages of ahope, and pegasus-plots is extremely useful in clearly
      displaying which jobs are running the longest and where we need to
