This PR depends on and, therefor, includes #817 and its dependencies.
This corresponds to the FilterRel message and the ones contained in
it. Since one of the messages is an Expression message, this PR also
introduces the ExpressionOpInterface as well as the LiteralOp as
well as the basic import/export infrastructure for such ops/messages.
The LiteralOp corresponds to the Expression.Literal message type,
and the ExpressionOpInterface encapsualtes common properties and
functionality of all types of Expression messages. Finally, the PR
also adds attribute constraints for typed attributes of the currently
supported types.
