* Update docs/submodules/releng from branch 'master'
  - Merge "JJB 2.0.X does not allow scenario to be passed here"
  - JJB 2.0.X does not allow scenario to be passed here

    With this change releng/jjb/* now passes on:
    Jenkins Job Builder version: 2.0.1 and 1.6.2

    Error:
    TypeError: write() argument must be str, not list
    Explanation:
    in jjb 1.6.2 it would allow the list in and then the job would convert
    the list into a literal string of "['var1', 'var2']"

    - 'compass-{scenario}-{pod}-daily-{stream}'
    Can have scenario passed, {scenario} is part of the job name
    so it knows which scenario to add.

    - 'compass-deploy-{pod}-daily-{stream}'
    cannot have scenario passed, there is not one job generated per scenario
    so its tryting to add "['senario1', 'scenario2', 'etc']" into the {scenario}
    value, which is not allowed.

    This worked on jjb 1.6.2 becasue we overwrite the scenario
    information later:
    - trigger-builds:
        - project: 'compass-deploy-{pod}-daily-{stream}'
          predefined-parameters: |
            DEPLOY_SCENARIO={scenario}

    jjb/armband/armband-ci-jobs.yml is very simillar to this job
    and passes a default, which works, so that is what I have done here:
       - string:
           name: DEPLOY_SCENARIO
           default: 'os-odl-nofeature-ha'

    addendum:
    removed scenario: '{scenario}' from
    'compass-{scenario}-{pod}-daily-{stream}'
    even though it is valid, Trevor rightly pointed out that there is
    nothing to consume this value.
