Currently just has key creation with namespace as a parameter.
Happy to add more.
key := dsutils.IncompleteKeyWithNamespace(model.OptionKind, "namespace", nil)
key := dsutils.NameKeyWithNamespace(model.OptionKind, "namespace", "Name", nil)
key := dsutils.IDKeyWithNamespace(model.OptionKind, "namespace", int64(Id), nil)
