[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.
