> Expose the TimeServiceProvider from the Task to each Operator.

> This change aims at simplifying the {{StreamTask}} class by exposing directly
> the {{TimeServiceProvider}} to the operators being executed.
> This implies removing the {{registerTimer()}} and
> {{getCurrentProcessingTime()}} methods from the {{StreamTask}}. Now, to
> register a timer and query the time, each operator will be able to get the
> {{TimeServiceProvider}} and call the corresponding methods directly on it.
> In addition, this will simplify many of the tests which now implement their
> own time providers.
