    [FLINK-2802] [streaming] Remove cyclic watermark dependencies for iterations

    This PR contains a simple change so that if timestamps are enabled, iteration sources
automatically emit a `Long.MAX_VALUE` watermark.
    
    While this will not help making event/processing time windows consistent across cycles
(which is inherently problematic due to the cyclic time dependency), at least these programs
will not deadlock.
    
    I still need to add a test to validate the behaviour.
