[DISCUSS] FLIP-42: Savepoint Connector

Hey Everyone!

Gordon and I have been discussing adding a savepoint connector to flink for
reading, writing and modifying savepoints.

This is useful for:

   - Analyzing state for interesting patterns
   - Troubleshooting or auditing jobs by checking for discrepancies in state
   - Bootstrapping state for new applications
   - Modifying savepoints such as:
      - Changing max parallelism
      - Making breaking schema changes
      - Correcting invalid state

We are looking forward to your feedback!

This is the FLIP:
