Create opensource containers for use in the pipeline

The pipeline currently uses various catchall images that should be optimized to work for a particular job. For example, jenkins-oscap-agent:1.1 still has a jenkins jnlp agent on board, and it gets used for most of the jobs that need python as well. This image should be split into a hardened python image, a hardened oscap agent, etc.. These images should be built in the DSOP project for public consumption.
