Updated remote object storage helpers with new WCT interfaces (#131) 

* Renamed RoamingSettings to ObjectStorage, updated to use new storage interfaces from WCT, and migrated to *.Graph package

* Applied updates from WCT ObjectStorage PR feed

* Updated dependencies and RoamingSettings namespace

* Updated and added tests
