Description

This issue reduces the evaluator memory size in unit test `CloseEvaluatorTest` and `AddOneTest` to reduce the test overheads in CI and Docker clusters.

• From 4GB (16 Evaluators x 256MB) to 1GB (16 Evaluators x 64MB).
  CloseEvaluatorDriver.java

  - .setNumber(NUM_EVALUATORS).setMemory(256).setNumberOfCores(1).build());
  + .setNumber(NUM_EVALUATORS).setMemory(64).setNumberOfCores(1).build());
  

• From 2GB (2 Evaluators x 1024MB) to 128MB (2 Evaluators x 64MB).
  AddOneTest.java

  - VortexConfHelper.getVortexConf("TEST_Vortex_AddOneTest", AddOneTestStart.class, 2, 1024, 4, 2000);
  + VortexConfHelper.getVortexConf("TEST_Vortex_AddOneTest", AddOneTestStart.class, 2, 64, 4, 2000);
  

Since `LocalTestEnvironment` overrides the number of evaluators of all unit tests with the maximum number of evaluators, 4, the requested resource of unit tests is not important so far. The above two tests are the most memory consuming unit tests.
