Review comment:
This command does not need any analysis and using `RunnableCommand`
should be good enough
```
case class ShowCurrentNamespaceCommand extends LeafRunnableCommand {
override def run(sparkSession: SparkSession): Seq[Row] = {
val catalogManager = sparkSession.sessionState.catalogManager
...
}
}
```
