> It would be nice to have 'show create' type of commands on the command-line so that it
would generate the DDL for the schema.
> A scenario that would make this useful is where a team works out a data model over time
with a dev cluster.  They want to use parts of that schema for new clusters that they create,
like a staging/prod cluster.  It would be very handy in this scenario to have some sort of
export mechanism.
> Another use case is for testing purposes - you want to replicate a problem.
> We currently have schematool for import/export but that is deprecated and it exports
into yaml.
> This new feature would just be able to 'show' - or export if they want the entire keyspace
- into a script or commands that could be used in a cli script.  It would need to be able
to regenerate everything about the keyspace including indexes and metadata.
