We need to serialize `formatPluginConfig` to be able to create
`MapRDBFormatPlugin` during deserialization.
`MapRDBFormatPluginConfig` contains five fields only:
```
public boolean allTextMode = false;
public boolean enablePushdown = true;
public boolean ignoreSchemaChange = false;
public boolean readAllNumbersAsDouble = false;
public boolean disableCountOptimization = false;
```
Regarding the change, DRILL-5714 fixed initially incorrect implementation
logic in `MapRDBSubScan`.
Current implementation is similar to `EasySubScan`.
