Role on default project should be selectable when creating user

[Gabriel Hurley]

We allow selecting the user's role when adding a user to a project, but not when creating a user and adding them to their default project. User research has shown that this is confusing and annoying because it leads to creating a user, going to the projects page, editing the members, removing that user and re-adding them to make them an admin.

As a bonus, we can remove the setting and hackery for the "keystone default role" when this is fixed.
