SystemsLab 0.0.45

Changed

• The SystemsLab runner will now output some host info into the logs at the start of every job run.
• The SystemsLab runner will now emit a warning to the logs if all steps have background=true.
• The /api/v1/artifact and /api/v1/experiment/:id/artifacts endpoints now return a consistent schema between.

Fixed

• The systemslab-postgresql upgrade process should now connect as the cluster owner instead of the database owner.
• The systemslab-nss install script no longer modifies /etc/nsswitch.conf in-place. This should solve some issues with sed experiencing errors.
• systemslab-agent should no longer fail to upload metrics to the server.
