Jim Apple d70ffa455d IMPALA-3450: LIMITs on plan nodes are reflected in cardinality estimates

PlanNode includes a 'capAtLimit()' method that can be used in
'computeStats()' on PlanNodes to ensure they do not estimate their
cardinality to be more than a pushed-down LIMIT clause.

This patch ensures that 'capAtLimit()' is used in all of the relevant
classes descending from PlanNode.

README

This directory contains Impala test workloads. The directory layout for the workloads should follow:

workloads/
   <data set name>/<data set name>_dimensions.csv  <- The test dimension file
   <data set name>/<data set name>_core.csv  <- A test vector file
   <data set name>/<data set name>_pairwise.csv
   <data set name>/<data set name>_exhaustive.csv
   <data set name>/queries/<query test>.test <- The queries for this workload
