Along those lines,     there are currently no constraints in the db to
enforce that everything has an assigned tenant.  I'd like to change that.

Currently,   it's possible to have tenancy turned on but still have NULL
tenant_id on a user, deliveryservice, or origin.  That leads to ambiguous
situations that can be painful to handle in code. Here's what I'd like to
suggest:

If the use_tenancy parameter is OFF (0),  set the tenant to ROOT for any
item without an assigned tenant.   If ON,   create a new tenant
("unassigned"?) and assign any NULL tenant ids to that instead -- this
allows the admin to easily find the stray ones and assign them
appropriately.   Once all those are assigned,  we can add the constraints
to the db to enforce tenancy.   Then,  we can do away with the code that
supports the use_tenancy flag and simplify the Traffic Ops code.

Thoughts?
