**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Once https://github.com/apache/arrow-datafusion/pull/2639 is merged we should add support for serializing plans that contain subquery expressions. This will likely require breaking changes to the API because we currently have one API for `Expr` that optionally accepts a `FunctionRegistry` and one API for `LogicalPlan` that optionally accepts a `LogicalExtensionCodec`. With subquery support we have plans referencing expressions and expressions referencing plans, so these APIs will need to be combined somehow. **Describe the solution you'd like** TBD **Describe alternatives you've considered** None **Additional context** None -- This is an automated message from the Apache Git Service.
