Remove public Jenkinsfile. Add public build status badge

[ButkiewiczP]

This PR accomplishes the following:

• Updates the README file with a working link/image to the Swift-Wisdom Build on Intrepid's CI server.
• Removes the public Jenkinsfile from the repository root in favor of a Jenkinsfile managed by Intrepid on the CI server itself. The jenkins pipeline has also been updated to use the latest version of the Intrepid pipeline library
