Manage Workspace role/permissions with Teammate Groups

Today teammate Groups can be used to grant access to a Workspace with the default access role. This means that if an admin wishes to grant any other role with a teammate Group, they must assign it to users individually. This can becomes messy and inefficient with large numbers of teammates, and reduces the benefits of using teammate Groups.

We could allow a role to be selected when granting a teammate Group access to a Workspace, making permission management more scalable.
