Log the identity of the worker in test job log files
With the arrival of lavafed and an increase in the use of
lava-slave in docker containers, it is now important to identify which test jobs were run on which worker, not just the version of lava-dispatcher. This needs to be a permanent part of the test job logs.
e.g. To tell the difference between:
- https://lava.codehelp.co.uk/scheduler/job/4483 and
- https://lava.codehelp.co.uk/scheduler/job/4489 or
- https://lava.codehelp.co.uk/scheduler/job/4478 (the jobs either side).
(Guessing based on the submitter isn't reliable.)
This may require
lava-slave passing this information to
lava-run. #114 (closed) will likely require the container name to be passed to
lava-run and this should be logged too.
