+1, I like the changes.
Concerning (7) - I think creating the state backend once sounds good. It is
more in line with the keyed state backend.
Concerning Aljoscha's comments: Removing SnapshotProvider makes sense, if
it is only an internal interface and never exposed to the user.
Conderning the name `OperatorState` - I actually like the name. It is state
that exists in the instance of an operator, assuming that functions are also
(special cases of) operators.
I would add to this pull request that it removes the deprecated
`OperatorState` interface (superclass of `ValueState`).
