Add Config

Moralis Config offers a convenient way to configure parameters in Cloud Code.
const config = await Moralis.Config.get({useMasterKey: true});
const privateParam = config.get("privateParam");
By default, Moralis Config parameters can be publicly read, which may be undesired if the parameter contains sensitive information that should not be exposed to clients.
A parameter can be made readable only with the master key by setting the Requires master key? property via the Moralis Dashboard to Yes.
