    [FLINK-6656] [cep] Change element PriorityQueue to MapState.

    This is to leverage the fact that RocksDB already returns the
    keys sorted. So now elements, instead of being stores in a PQ
    and all of them being deserialized and serialized at each incoming
    element, the are stored in a MapState with the key being the
    timestamp and the value, a List of elements that refer to the
    same timestamp.
