[FLINK-8978] Stateful generic stream job upgrade e2e test
## What is the purpose of the change
e2e test for generic state job upgrade and state recovery based operator
uid.
## Brief change log
- extract `DataStreamAllroundTestJobFactory` from
`DataStreamAllroundTestProgram` to reuse generic components and their cli
config.
- extract some code snippets into functions from
`test_scripts/test_resume_savepoint.sh` to `test_scripts/common.sh` to reuse
them in this new test
- add `flink-stream-stateful-job-upgrade-test` module to flink e2e tests
- add `StatefulStreamJobUpgradeTestProgram` which is constructed from
`DataStreamAllroundTestJobFactory`
- add `test_scripts/test_stateful_stream_job_upgrade.sh` to
`run-nightly-tests.sh`
## Verifying this change
run from flink repo root
```bash
$ mvn clean package
$ FLINK_DIR=build-target
flink-end-to-end-tests/test-scripts/test_stateful_stream_job_upgrade.sh
```

> Key: FLINK-8978
> URL: https://issues.apache.org/jira/browse/FLINK-8978
> Project: Flink
> Issue Type: Sub-task
> Components: Tests
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Assignee: Andrey Zagrebin
> Priority: Blocker
> Fix For: 1.6.0, 1.5.1
>
>
> Job upgrades usually happen during the lifetime of a real world Flink job.
> Therefore, we should add an end-to-end test which exactly covers this
> scenario. I suggest to do the follwoing:
> # run the general purpose testing job FLINK-8971
> # take a savepoint
> # Modify the job by introducing a new operator and changing the order of
> others
> # Resume the modified job from the savepoint
> # Verify that everything went correctly
