Auto-select persona

Provide the ability for an user to automatically impersonate a persona. Use case: jdoe creates "Red Hat, Inc" organization and wants to only manage resources under this organization. Thus, switching to "Red Hat, Inc" every time after logging in is error prone and unnecessary.

Possible approaches:
1) Provide a "settings" page, where the user selects the persona
2) Automatically select the last used persona.
