[FLINK-1003] Added spread out scheduling strategy
The spread out scheduling strategy tries to keep the work load among the
instances balanced. The scheduling strategy can be specified by the
configuration parameter ```jobmanager.scheduling-strategy```. Valid options are
```SpreadOut``` and ```FillFirst```. The latter strategy is the old and default
strategy.

> Project: Flink
> Issue Type: Improvement
> Reporter: Till Rohrmann
>
> Currently the Flink scheduler tries to fill one instance completely before
> the tasks are deployed to another instance. This is a good behaviour in
> multi-user and multi-job scenarios but it wastes resources if one wants to
> use the complete cluster. Therefore, another scheduling strategy where the
> load among the different instances is kept balanced might be useful. This
> spread out strategy will deploy the tasks such that the overall work is
> equally distributed.
