/*
 * This pipeline is the "template" for the Asterisk REF_DEBUG Tests multi-branch
 * parent job.  Jenkins will automatically scan the branches in the "asterisk"
 * or "Security-asterisk" projects in Gerrit and automatically create a branch-
 * specific job for each branch it finds this file in.
 *
 * This file starts as a declarative pipeline because with a declarative
 * pipeline, you can define the trigger in the pipeline file.  This keeps
 * everything in one place.  We transition to scripted pipeline later on because
 * we need to dynamically determine which docker image we're going to use and
 * you can't do that in a delcarative pipeline.
