    [FLINK-8477][Window]Add api to support user to skip serval broken window

    In production, some application like monitor type , it need the accuarcy 
data,but in this scenario: if we start a job at 10:45:20s with a 1min window 
aggregate, we may produce a broken data of 10:45min ,so may lead to mistake. We 
can support a user api to choose to skip serveral windows to avoid the broken 
data by user self.
    
    ## Brief change log
    
      - add a streaming api
