Luca Cavanna 747fa721e4 Build: add client jar for aggs-matrix-stats ()
This will be useful for the high level client to add support for the matrix stats aggregation, as we will ship with this jar by default like we do for parent-join-client which is aligned with distributing core with the modules already included.

Nicholas Knize f449666c59 New Matrix Stats Aggregation module
This commit adds a new aggs-matrix-stats module. The module presents a new class of aggregations called Matrix Aggregations. Matrix aggregations work on multiple fields and produce a matrix as output. The first matrix aggregation provided by the module is matrix_stats aggregation. This aggregation computes the following statistics over a set of fields:

* Covariance
* Correlation

For completeness (and interpretation purposes) the following per-field statistics are also provided:

* sample count
* population mean
* population variance
* population skewness
* population kurtosis
