MANUAL BACKPORT.

This was not backported when the original PR was pushed. The milestone was pushed back
afterward.

ipa-4-6 still defines:
WSGI_PROCESSES=constants.WSGI_PROCESSES,

---------
When non-admin user issues a command that utilizes
api.Object.config.show_servroles_attributes(), some server roles might
return errors.EmptyResult, indicating that a role is not visible to this
identity.

Most of the callers to api.Object.config.show_servroles_attributes() do
not process errors.EmptyResult so it goes up to an API caller. In case
of Web UI it breaks retrieval of the initial configuration due to ipa
config-show failing completely rather than avoiding to show available
server roles.
