Artisans need to be able to create & maintain Gallery connections

[capgroup]

As a Curator, I need Artisans to be able to create & maintain their own Gallery connections (rather than only Curators)

- My Artisans use their own credentials in their connections

- Their credentials are subject to a periodic reset policy, so they need a self-service capability to update their connection credentials (and sharing settings)

We'd like to see this functionality for similar reasons.  Currently I (as gallery curator) must meet with the user, grant them temporary curator rights (not ideal), let them create the connection and then set them back to artisan. 

Would like to grant them rights to create and share their own gallery data connections without having to loan-out the keys to the kingdom.
