Unblocked - now that we can discuss workflows!

We need to think through roles both in conda-store and how this relates to Nebari.

On the conda-store side - we need to make sure that we have conda-store role distinctions that can edit or only view - We believe this exists, @steff456/ @nkaretnikov will define what is available.

On the Nebari side - we need to make sure that we have nebari role distinctions that can edit or only view - the relationship between these two roles needs to be explored.

This work should be done with the changes that are being implemented in conda-incubator/conda-store#491 in mind.
