Thanks for making this PR @jedwards4b we'll discuss at our weekly meeting.

Because this includes submodule updates, this will likely need to follow some other PR's with submodule updates. And the tags for submodules will all need to be done before merging.

[ekluzek]

This is straightforward and makes sense to me.

I rebased this to b4b-dev, and maybe the way to do this one, would be to bring this one as it is, and then do the other submodule updates in a different PR. They don't have to be connected together, although they all need to come together in a final tag to get the benefits.

@ekluzek will merge this to b4bdev and create issues for the definition of done wrt other components
