[FLINK-3965] [gelly] Delegating GraphAlgorithm
A DelegatingGraphAlgorithm wraps a GraphAlgorithm result with a delegating
proxy object. The delegated object can be replaced when the same algorithm is
run on the same input with a mergeable configuration. This allows algorithms to
be composed of implicitly reusable algorithms
without publicly sharing intermediate DataSets.

> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Affects Versions: 1.1.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Fix For: 1.1.0
>
>
> Complex and related algorithms often overlap in computation of data. Two such
> examples are:
> 1) the local and global clustering coefficients each use a listing of
> triangles
> 2) the local clustering coefficient joins on vertex degree, and the
> underlying triangle listing annotates edge degree which uses vertex degree
> We can reuse and rewrite algorithm output by creating a {{ProxyObject}} as a
> delegate for method calls to the {{DataSet}} returned by the algorithm.
