This patch adds support for COS(Cloud Object Storage). Using the hadoop-cos, the implementation is similar to other remote FileSystems. New flags for COS: - num_cos_io_threads: Number of COS I/O threads. Defaults to be 16. Follow-up: - Support for caching COS file handles will be addressed in IMPALA-10772. - test_concurrent_inserts and test_failing_inserts in test_acid_stress.py are skipped due to slow file listing on COS (IMPALA-10773). Tests: - Upload hdfs test data to a COS bucket. Modify all locations in HMS DB to point to the COS bucket. Remove some hdfs caching params. Run CORE tests.
