This closes #5112.

The flip6 build profile only runs the Flip-6 related test cases. Moreover,
all Flip-6 related test cases are excluded when not running the flip6 build
profile. This should reduce testing time when adding more and more Flip-6
test cases.

Include flink-test-utils-junit in all submodules to make the Category marker interfaces Flip6 and OldAndFlip6 available

..capable of tracking min, max and estimates for count distinct and
heavy hitters.

The count distinct algorithms are Linear Counting and HyperLogLog, both
from an imported library from clearspring.

The heavy hitters algorithms are Lossy counting (Manku et.al 2002) and
one based on Count Min Sketch (Cormode 2005).

The heavy hitters algorithms are implemented in the statistics package
in the flink-operator-stats submodule of flink-contrib.

Include tests verifying if merged skecthes have the same guarantees as
local sketches.

Added conditional to every collect variable, to make stats more
configurable. Made print operator stats more informative. Added
arguments to yarn pom to enable building

Implemented deep cloning for class OperatorStatistics. Added additional
tests in OperatorStatsAccumulatorTest to check if the accumulator works
when only one statistic is being tracked, rather than all.

This closes #605.
