It looks like squash isn't accepting the results:

400 Client Error: BAD REQUEST for url: ****jobs/

script returned exit code 1

From looking at the source, I'm guessing we're banging into a 16 char limit of the ci_label field. Previously, this was being set to the jenkins node label the sub-configuration was running, which was always centis-7. As part of the rewrite, I'm not setting this to the registry url of the docker image (eg., ocker.io/lsstsqre/centos:7-stack-lsst_distrib-d_2017_11_16).
