@dianfu I agree that we should consider removing states from serialization,
but I have some concerns about it:
1. `State`s are part of `ComputationState`s which describe partial matches,
which means they are definitely not metadata. If we do not want to store
`State`s, I think we will be forced to either drop checkpointing of partial
matches or implement logic of translating them to newly constructed graph of
states, which I think would be hard if possible at all.
2. One feature I would like to see in FlinkCEP library is dynamically
providing new Patterns(e.g. through Side Inputs), I think in this case `State`s
serializing will be crucial.
