Avoid additional totalRecords SQL query for offset=0 limit=MAX_INT

CqlQuery’s get(String cqlQuery, int offset, int limit) method always executes the additional SQL query that calculates the totalRecords estimation.

This additional SQL query is not needed and should not execute if offset=0 and limit=MAX_INT because the main SQL query returns all records so that the exact totalRecords number can easily been determined from the result set size.
