Add suplementary rake tasks for distributed hll
What does this MR do?
It aim to provide supplementary rake tasks to conduct robust HyperLogLog implementation accuracy analysis
Proposed rake tasks uses statistical methods that assess accuracy of algorithm implementation over big set of algorithm estimation, instead of single run that is pron to be skewed by probabilistic nature of algorithm.
In original paper http://algo.inria.fr/flajolet/Publications/FlFuGaMe07.pdf mathematical method used to asses accuracy was relative standard error
Implements: #299184 (closed)
