Run thermos jobs using json client.

Added an extra field to JobJson, ExecutorDataFile, that holds
the path to the json file representing the executor configuration
data.
Added a new example job json file (examples/job_thermos.json) that
is to be passed to the json client along with the config file to
run a thermos job.
