    Correct the project domain option for authorization

    In blazar configuration, we have the following options:

    * os_admin_user_domain_name
    * os_admin_project_domain_name

    They are used for Keystone authentication, but
    ``os_admin_project_domain_name`` in the configuration file was not
    reflected in Blazar. This is because the Blazar service used
    ``os_admin_user_domain_name" for both *project* and *user* domain name.

    This patch fixes the bug and adds related tests.
