Jetlag CI stuff

[webbnh]

This PR creates a holding area for materials which might be used to create a Jetlag continuous integration (CI) system, to automate building and testing of Jetlag for development and quality assurance.

This PR, in addition to adding a CI subdirectory and a README.md for it, adds one file, deploy_sno.sh, which is an initial effort at scripting the deployment of a single-node OpenShift cluster using Jetlag. It is targeted at a Scale Lab deployment, but the techniques it uses should be applicable across all deployments. It is currently somewhat opinionated, but it should be straightforward to generalize it.

This PR is not necessarily intended to be merged; rather, it's a placeholder, to give visibility for this file in the event that someone wants to use it as the basis for a CI runner, e.g., for Jenkins.
