Refactor inherited test cases (e.g., VnePmMigration)

Currently, there are various test classes that inherit a super test class and just overwrite the method to create a new algorithm instance to test. As this is a bad coding style, one may refactor the test cases to parametrized tests to remove the high number of classes for each test case.

Example file: https://github.com/maxkratz/iflye/blob/1bc84da8d29f8ef0b6f89b848bca2d90db743fe0/test.suite/src/test/algorithms/pm/migration/VnePmMdvneAlgorithmMigrationTotalCommunicationCostATest.java#L21

Start with test.suite/src/test/algorithms/pm/migration/VnePmMdvneAlgorithmMigrationTotalCommunicationCostATest.java and inspect its inherited superclass and related migration test classes. Identify the repeated subclasses that only create a different algorithm instance, then review how Java parameterized tests can represent those cases. Done means the redundant test classes are removed or consolidated and the migration tests still pass.
