URL: https://github.com/apache/flink/pull/22593
## What is the purpose of the change
This PR is a subtask of FLIP-292 to enable operator-level state TTL
configuration via `CompiledPlan`.
## Brief change log
Introduce `StateMetadata` to all `ExecNode`s that translate to stateful
operators, and changes the way how `#translateToPlanInternal` get the state
retention time.
The affected `ExecNode` list
```
StreamExecChangelogNormalize
StreamExecDeduplicate
StreamExecGlobalGroupAggregate

StreamExecIncrementalGroupAggregate
StreamExecJoin
StreamExecLimit
StreamExecLookupJoin
StreamExecRank
StreamExecSink
StreamExecSortLimit
```
## Verifying this change
Since we have upgraded some `ExecNode`s to version 2, we have to test the
following 3 parts:
1. The plan serialized using version 1 can be deserialized using the current
version. This can be verified by `TransformationsTest#testUidFlink1_15`
2. The plan with the current version SerDe work as expected. This can be
verified by all tests under package
`org.apache.flink.table.planner.plan.nodes.exec.stream`
3. The way by modifying the JSON content to change state TTL works as
expected. This can be verified by ITCase
`ConfigureOperatorLevelStateTtlJsonITCase`
