Currently errors in docker image builds fail the entire build. Docker
images are in flux, and are likely to cause every build to fail.
Workaround: don't fail the main build if some docker images failed (but
print out a warning in Jenkins log).
Changes:
- Ignore docker image build errors with a warning
- Misc changes to scripts to make sure various steps happen in the right
order
