Extra docker run args are ignored when provided in YAML spec

Issue Summary

Extra docker run args are ignored when provided in YAML spec

Steps to Reproduce

1. Import YAML spec in a repository with bamboo-specs/bamboo.yaml that has:

Default Job:
  key: JOB1
  docker:
    image: ubuntu
    volumes:
      ${bamboo.working.directory}: ${bamboo.working.directory}
      ${bamboo.tmp.directory}: ${bamboo.tmp.directory}
    docker-run-arguments:
    - --net=host

2. Run specs scan.

Expected Results

The created plan, namely docker runner config should container extra args --net=host

Actual Results

Docker run args are ignored. The resulting yaml looks like this:

      dockerConfiguration:
        dockerRunArguments: []
        enabled: true
        image: ubuntu
        volumes:
          ${bamboo.working.directory}: ${bamboo.working.directory}
          ${bamboo.tmp.directory}: ${bamboo.tmp.directory}

Workaround

Install attached patch:

1. Shutdown the Bamboo server
2. Locate <bamboo_install_dir>/atlassian_bamboo/WEB-INF/lib/atlassian-bamboo-import-export-7.1.1.jar.
3. Replace it with the jar file attached to this ticket (it's recommended to make a backup of the original file)
4. Start the server again
5. Re-scan any YML Specs affected by this issue.
