MAHOUT-1976 Add CanopyClustering
MAHOUT-1976 Add Canopy Clustering
### Purpose of PR:
1 . Primarily, this PR adds CanopyClustering to Algorithms Framework.
2. This PR introduces the "clustering" framework of the algorithms framework
3. this PR introduces distance metrics and ports two metrics from the old
MR code base.
### Important ToDos
Please mark each with an "x"
- [x] Opening PR against `develop` NOT `master` (OR `feature-name` if this
is part of an ongoing feature development). **need to delete this requirement,
JIRA needed**
- [x] A JIRA ticket exists (if not, please create this
first)[https://issues.apache.org/jira/browse/ZEPPELIN/]
- [x] Title of PR is "MAHOUT-XXXX Brief Description of Changes" where XXXX
is the JIRA number.
- [x] Created unit tests where appropriate
- [x] Added licenses correct on newly added files
- [x] Assigned JIRA to self
- [x] Added documentation in scala docs/java docs, (and website once that
is merged to dev)
- [x] Successfully built and ran all unit tests, verified that all tests
pass locally.
Oh by the way, does this change break earlier versions?
No
Is this the beginning of a larger project for which a feature branch should
be made?
No

> Key: MAHOUT-1976
> URL: https://issues.apache.org/jira/browse/MAHOUT-1976
> Project: Mahout
> Issue Type: Improvement
> Components: Algorithms
> Affects Versions: 0.13.2
> Reporter: Trevor Grant
> Assignee: Trevor Grant
>
> Primarily, we need to lay out the clustering section of the Algorihtms
> Framework.
> The Canopy Clustering Algorithm is very simple and yet very useful as a
> preprocessing step for more advanced clustering algorithms such as KMeans and
> Hierarchical Clustering.
> https://en.wikipedia.org/wiki/Canopy_clustering_algorithm
> The majority of the "work" on this PR will be creating the framework.
> It is also one of the Legacy MR algorithms that would be nice to port.
