Realize that the deserialize method need an registry to dispatch types. I
plan to add an field in `SessionState` to do that. It looks like
```rust
pub trait ExtensionDeserializer {
fn deserialize_logical_plan(
&self,
name: &str,
bytes: &[u8],
) -> Result<Arc<dyn UserDefinedLogicalNode>>;
// Won't be added this time
fn deserialize_physical_plan(
&self,
name: &str,
bytes: &[u8],
) -> Result<Arc<dyn ExecutionPlan>>;
}
```
