Added test cases in ConfKeyManagerTestCase to verify fixed_key.

ConfKeyManagerTestCase sets the fixed_key option, but does not

appropriate unit test cases to verify the fixed_key option.

should be done directly against the neutron API, rather than
using nova-manage.

Fix up import of conductor

Need to import API from nova.conductor not from nova.conductor.api
directly. This is needed so the is_local flag can be used to
determine the conductor API to use (local or rpc)
