'keystone-manage endpoint add myTenant nova' appears to succeed

[Mark McLoughlin]

Doing something like this:

  $> keystone-manage endpoint add myTenant nova

and it appears to work. We should validate that the endpointTemplate arg is a valid endpointTemplate ID.

I now get:

$ ./keystone-manage endpoint add myTenant nova
ERROR: 'NoneType' object has no attribute 'id'
Traceback (most recent call last):
  File "./keystone-manage", line 18, in <module>
    keystone.manage.main()
  File "/Users/ziadsawalha/Documents/Code/keystone/keystone/manage/__init__.py", line 464, in main
    raise exc
AttributeError: 'NoneType' object has no attribute 'id'

We need to improve on the messaging (planning that for E3).
