providing groups do not occur when getting/(listing) ruleset(s)

[QingchuanHao]

when I try to get providing groups from rule set, I find there is no providing groups entry in the shell output, so did api requests.

I did not find any comment or document that tell me providing groups should be escaped from rule set.

    Add providing groups attribute of rule set in resource map

    When we list/get rule set, no providing groups occur,
    as a result of providing group attribute missing in rule set.

    This patch fix this by adding providing group attribute in rule set.
