Add support to run tests in a user-specified single tenant

Currently each test suite creates its own projects/users
In production test environments, the admin could allocate
a specific project where the tests are expected to run
(In env.test dict, stack_user, stack_password and stack_tenant
in testbed.py)

Ex testbed.py changes:
env.test = {
'stack_user': 'testuser',
'stack_password' : 'testuser123',
'stack_tenant' : 'testproject',
'tenant_isolation' : False,
}
