title: Return parameters/results from a job(triggered by pipeline) back to the same pipeline
body: <p>Jenkins pipeline: I have a pipeline <code>p1</code> that triggers a job <code>j1</code> and then job <code>j2</code>. I want some parameters that are set by <code>j1</code> and passed to <code>j2</code> in pipeline <code>p1</code>. How do I implement this functionality using Jenkins pipeline plugin? Thanks in advance</p>
