Description

Merge regex parser and calcite parser into one parser. It will first use regex to match simple commands, e.g. SET Commands. If the regex doesn't find any avaliable commands, the statement will be delegated to the underlying Calcite parser. In this way, we can use tableEnv.executeOperation to execute parsed operation.
