@zentol Thanks again for your thorough review!
What do you think about my earlier comment regarding unification:
```
About unifying the functionality of the tests/ITCases, I was planning to to
that for the upcoming *From13 tests but for the *From11 and *From12 it's
difficult because quite some stuff changed between 1.1 and 1.2 and I want the
code to mostly work on all branches. For example, this is the new *From12 tests
rebased on the master branch:
https://github.com/aljoscha/flink/tree/jira-5969-backwards-compat-12-13. By
transplanting but keeping the snapshots that were generated on Flink 1.2.0 we
get backwards compatibility tests while the tests in this PR test compatibility
within Flink 1.2.x.
```
> Add savepoint backwards compatibility tests from 1.2 to 1.3
