Amnon Heiman 9dae28e2f0 ColumnFamilyStore: finishLocalSampling should respect count limit
When calling nodetool toppartitions with size limit, finishLocalSampling
should respect that and limit the number of the results.

Example:
$ nodetool toppartitions -k 2 keyspace1 standard1 20
WRITES Sampler:
  Cardinality: ~2 (256 capacity)
  Top 2 partitions:
	Partition                Count       +/-
	38333032394d4f4d5030         4         3
	4e353937383137503330         4         3

READS Sampler:
  Cardinality: ~2 (256 capacity)
  Top 2 partitions:
	Nothing recorded during sampling period...

Fixes #66
