Update git submodules

Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "Update Functest jobs (please vote an do not merge)"
  - Update Functest jobs (please vote an do not merge)

    We are going to try this again. Once this is merged, I will need
    to delete all the jobs that change job type and then re-merge
    releng merge will be broken during this short window.

    --- original commit message ---
    Add support for functest tier with multijob
    Add publishers separate for fetures and
    all other functest tiers
    Run functest features suits in a mutijob
    Since there are no arm specific requirements,
    remove arm-daily builders and jobs
