[FLINK-7124] [flip-6] Add test to verify rescaling JobGraphs works correctly
## What is the purpose of the change
This pull request adds test to verify that rescaling `JobGraph`s to
arbitrary valid DOPs works correctly, such that the generated `ExecutionGraph`
of each rescale is correct.
## Brief change log
- Add `ExecutionGraphRescalingTest` class.
- Contains a test that consecutively rescales (up and down) a given
`JobGraph`.
- Contains a test that rescales to DOP beyond max parallelism. `TODO`
ignored for now since the test doesn't properly fail as expected.
- `[hotfix]` refactor `ExecutionGraphConstructionTest` to share utility
graph validation code.
## Verifying this change

[FLINK-7124] [flip-6] Add test to verify rescaling JobGraphs works correctly
This commit adds two tests to verify behaviours of rescaling JobGraphs:
1. JobGraphs can be consecutively rescaled to arbitrary valid DOPs
2. Rescaling beyond max parallelism would fail
The second test, however, is temporarily disabled for now since it
doesn't properly fail.

[hotfix] Refactor graph verification code in ExecutionGraphConstructionTest
The refactoring resuses utility methods in ExecutionGraphTestUtils to
verify constructed ExecutionGraphs.
