Add tab completion for ALTER USER/ROLE RESET

Browse Source 
Currently tab completion for ALTER USER RESET shows a list of all
configuration parameters that may be set on a role, irrespectively of
which parameters are actually set. This patch improves tab completion to
offer only parameters that are set.
