Several refactors were done on the data storage layer of jslib to support Account Switching for desktop.
These changes have been implemented here for parity across clients, improved readability, and to make it easier
to add Account Switching to other clients later if desired.
* The UserService was removed, and so all references have been replaced with the new access points for that data (activeAccount and organizationService most often)
* The StorageService is now considered a "global" scope, where as we have a new "account" scope to consider. Any "account" scope storage items I have moved to saving with
an ActiveAccountService instance instead of a StorageService instance.
* ConstantsServices have been removed and replaced with a StorageKey enum that holds keys that were in ConstantServices and in other feature scoped services.
