URL: https://github.com/apache/flink-ml/pull/148
## What is the purpose of the change
- Add AlgoOperator for AgglomerativeClustering[1] in Flink ML.
## Brief change log
- Added AlgoOperator for AgglomerativeClustering.
- Added java/python test/example for Transformer and Estimator for
KBinsDiscretizer.
- Comparing with Sklearn [1], we made the following changes:
- The distance between two data points in sklearn could be
`precomputed`, but we do not support this option in this PR
- sklearn uses `memory` to cache the output of the computation of the
tree`, but we do not support this in this PR.
- sklearn uses `connectivity` to define for each sample the neighboring
samples, but we do not support this in this PR.
