    [FLINK-1515]Splitted runVertexCentricIteration into createVertexCentricIteration and runVertexCentricIteration

    I changed the process for running a vertex-centric iteration in Gelly into a two-step
procedure:
    1. `createVertexCentricIteration` returns a `VertexCentricIteration` object to allow developers
to access features like broadcast data sets and  aggregators.
    2. `runVertexCentricIteration` expects a `VertexCentricIteration` and returns the `Graph`.

    Splitted runVertexCentricIteration into createVertexIteration and runVertexIteration to
make VertexCentricIteration object accessible to developers.

> Currently, aggregators and broadcast sets cannot be accessed through Gelly's  {{runVertexCentricIteration}}
method. The functionality is already present in the {{VertexCentricIteration}} and we just
need to expose it.
> This could be done like this: We create a method {{createVertexCentricIteration}}, which
will return a {{VertexCentricIteration}} object and we change {{runVertexCentricIteration}}
to accept this as a parameter (and return the graph after running this iteration).
> The user can configure the {{VertexCentricIteration}} by directly calling the public
methods {{registerAggregator}}, {{setName}}, etc.
