[FLINK-8976] [test] Add end-to-end test for resuming savepoints with
different parallelism
## What is the purpose of the change
This PR adds end-to-end tests for resuming a savepoint with different
parallelisms.
## Brief change log
The changes are based on the new `test_resume_savepoint.sh` test script in
#5733, so only the last commit is relevant.
That script has been modified to be able to specify parallelism of the
state machine job, before and after the savepoint restore.
- Adapt `test_resume_savepoint.sh` to be able to use different parallelism
after the savepoint restore.
- Add scale up / scale down tests to be executed by Travis.
