Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Projects did not fill out their releases/fraser/

    This is the patchset of projects that did not fill out their
    releases fraser file.

    I have done it for them.
    some of the projects had no changes on the fraser branch
    in this case I put the tag in the same place as the 6.0.0 tag

    some project I am familliar with and I move the tag to the
    head of fraser for them,

    Ideally team leads will do this work in the future
    We will update the tagging instructions accordingly.
