--------------------------------------------------------------------

We should also append the token stuff to the users query if they don't put it there.  As without
the token stuff the query is not going to do what the user expects.  (Related to CASSANDRA-7725)

> Inorder to ease migration from CqlPagingRecordReader to CqlRecordReader, it would be
helpful if CRR input_cql defaulted to a select statement that would mirror the behavior of
CPRR.
> For example for a give table with partition key `((x,y,z),c1,c2)`
> It would automatically generate
> {code}
> input_cql = SELECT * FROM ks.tab WHERE token(x,y,z) > ? AND token (x,y,z) <= ?

> {code}
