Paul Glass b82b3c03d9 Zone ownership tests
* There are three tenants: default, alt, and admin
* Updated config to grab creds for each tenant type
* Reworked clients to make tenant selection simple within test cases
* Added zone ownership test cases
* A bit of other refactoring to put code in more sensible places
