Description:
Currently the keyed and non-keyed operators in the CEP library have different
implementations. This issue targets to unify them into one.
This new implementation will always be applied on a keyed stream, and in the
case of non-keyed usecases, the input stream will be keyed on a dummy key, as
done in the case of the {{DataStream.windowAll()}} method, where the input
stream is keyed using the {{NullByteKeySelector}}.
This is a first step towards making the CEP operators rescalable.
