// This Jenkinsfile will build a builder image and then run the actual build and tests inside this image
// It's very important to not execute any scripts outside of the builder container, as it's our protection against
// external developers bringing in harmful code into Jenkins.
// Jenkins will only run the build if this Jenkinsfile was not modified in an external pull request. Only branches
// which are part of the Dash repo will allow modification to the Jenkinsfile.
