Description of problem:

I created several types with admin user, created tenants and user which is a member in one of the tenants that I created.
I logged in with the user I created and was able to list and use all types. 

I can think of several reasons why we should not allow this, here are two from the top of my head: 

1. if we simply manage groups in our company it may cause a problem if a volume created by someone in finance is tagged for someone in support. 
2. if I use the type for customers name in a cloud, I may not want every one to see the customer names.

Version-Release number of selected component (if applicable):

openstack-cinder-2013.1.2-3.el6ost.noarch

How reproducible:

100%

Steps to Reproduce:
1. create a type as admin user
2. create a tenant with user which is member
3. log in as the user -> run: cinder type-list

Actual results:

we see all the types and can use them to create a volume 

Expected results:

a user should only see types that are assigned to them
