Title: Tenant separation fixes

Performed review of tenant separation, added in permissions checks that do the following:

* One set of checks needed for 'loggedin' scenarios, where the definition of 'loggedin' has changed to 'logged in to the target tenant
* Added the ability to determine if two tenants can "interact", which leverages tenant privacy rules
* Added configuration point to mark a tenant as 'private'. By default, tenants are public.
