Description

At the moment the entire cqlsh syntax rules are defined in one single field in https://github.com/apache/cassandra/blob/13b7362494c4c0ff3c5ce80b8e7ee7fe64d65785/bin/cqlsh.py#L313-L426.

It would be easier if every syntax rule would be stored in its own field for easier extensibility / customizability.

It probably also makes sense to move the relevant cqlsh syntax rules and syntax completer into a separate cqlshhandling.py module because cqlsh.py in itself is huge.
