We need a sync job to align upstream changes in Che repos to downstream CRW ones.

Should be simple enough to copy what we're doing for machine exec and then tweak files to rsync, sed transforms, and the injected brew metadata.

Upstream:
https://github.com/redhat-developer/kubernetes-image-puller/

Midstream (where the Jenkinsfile will live):
https://github.com/redhat-developer/codeready-workspaces/tree/master/dependencies

Downstream:
http://pkgs.devel.redhat.com/cgit/containers/codeready-workspaces-imagepuller/tree/?h=crw-2.0-rhel-8
