python: add set type for ovs.idl.data.Datum.from_python

ovs.db.idl.Datum.from_python fails to handle set type value, while set
type is also a common iterable sequence, just like list and tuple.
No reason IDL caller must to turn set type parameters to list or tuple
type. Otherwise, they will fail to insert data, but get no exception.
