SystemsLab 0.0.2

Added

• You can now upload artifacts during a job run using the upload-artifact step type.
• You can now synchronize multiple job runs in the same experiment using the barrier step type.

Changed

• The systemslab agent now sets environment variables containing the ip addresses of other job runs within the same experiment.
• Dead agent entries are now periodically cleaned up in the background.
• Getting log events for a job run will now include some events in the past. This mitigates a race condition between starting a job and listening to its log events.
