[11/11] systemml git commit: [SYSTEMML-2496] Skip MapReduce tests as it is in maintenance mode

Posted by ni...@apache.org.
[SYSTEMML-2496] Skip MapReduce tests as it is in maintenance mode

- This commit makes hybrid_spark as default runtime for junit tests to increase the coverage of our spark backend.
- The FrameConverterTest and parfor tests are kept as is and can be modified in subsequent commits.
- The MapReduce tests can be turned on using TEST_MR_BACKEND flag in AutomatedTestBase class.
- We only disable HADOOP runtime and not HYBRID runtime. We can disable latter in subsequent commit.
