Fix bug 921814 changes handling of adminPass in API.

Add a new nova configuration flag, boolean, enable_instance_password.

When the flag is True (default), existing behavior is unchanged.

When the flag is False, responses from the create or
rebuild API calls don't include the adminPass attribute.
