title: Can a Jenkins Pipeline pass control to another Jenkinsfile?
body: <p>We have a monorepo containing several related projects. Depending on which project triggered the build, a different set of projects need to be built. These projects all have their own Jenkinsfile which builds and deploys just that project.</p>
  
  <p>I'd like to make a top-level Jenkinsfile which basically acts as a router. Have a small switch statement to build a list of projects to build in the right order and then kick off each of those Jenkinsfiles sequentially.</p>
  
  <p>Is this possible? Thanks.</p>
