Kostas Kloudas updated FLINK-4433:
----------------------------------
    Description: 
With the addition of continuous file monitoring, apart from the 
{{StreamSource}} also the {{ContinuousFileReaderOperator}} uses a 
{{SourceContext}}. Given this, all the implementations of the {{SourceContext}} 
should be removed from the {{StreamSource}} and become independent classes.

In addition, the {{AsyncExceptionChecker}} interface should be removed as its 
functionality can be replaced by the {{task.failExternally()}} method. This 
also implies slight changes in the source context implementations. 

Also in the {{trigger()}} method of the {{WatermarkEmittingTask}}, all the 
{{owner.getCurrentProcessingTime()}} could be replaced by the {{timestamp}} 
argument of that method.
