This patch adds support for huawei OBS (Object Storage Service) FileSystem. The implementation is similar to other remote FileSystems. New flags for OBS: - num_obs_io_threads: Number of OBS I/O threads. Defaults to be 16. Testing: - Upload hdfs test data to an OBS bucket. Modify all locations in HMS DB to point to the OBS bucket. Remove some hdfs caching params. Run CORE tests.
