Ability to reference relative file for "jobs:" configuration

Current jobs: looks like this:

jobs:
  - script: >
      multibranchPipelineJob('configuration-as-code') {
          branchSources {
              git {
                  id = 'configuration-as-code'
                  remote('https://github.com/jenkinsci/configuration-as-code-plugin.git')
              }
          }
      }

I would much prefer to have it reference files.

jobs:
   files:
      - job1.groovy
      - ./other/job2.groovy

I my experience, no seed job is quite as simple as the example. When attempting to migrate an existing server to JCASC one of my biggest stumbling blocks was converting/escaping/updating existing jobdsl. If jcasc supported loading of groovy files then I could almost just copy existing jobdsl and use it with almost zero effort on my part.

The advantage of this is that:

• remove the need for any escaping
• can use a groovy aware editor for jobdsl
• can easily test jobdsl in Jenkins or with other tools (without need for unescape/escape cycle
• greatly simplify migration to JCASC by allowing easy re-use of existing scripts.

try:

jobs:
  - file: /some/path/jenkins/can/get/to/file.groovy
  - file: /some/other/file.groovy

*EDIT: the file has to be avaialbe to the jenkins master, I put it in $JENKINS_HOME. You can also use - url: http://some/file.groovy. Found this by reading the source in support/src/main/java/io/jenkins/plugins/casc/support/jobdsl; This could probably be documented in the jobs section of the demos.

Seems to be documented here:

Does not work me when using the jenkins/jenkins:2.235.1 Docker image.
