creating external jdbc table
This patch builds on top of IMPALA-5741 to copy the jdbc jar from
remote filesystems: Ozone and S3. Currenty we only support hdfs.
Testing:
Commented out "@skipif.not_hdfs" qualifier in files:
- tests/query_test/test_ext_data_sources.py
- tests/custom_cluster/test_ext_data_sources.py
1) tested locally by running tests:
- impala-py.test tests/query_test/test_ext_data_sources.py
- impala-py.test tests/custom_cluster/test_ext_data_sources.py
2) tested using jenkins job for ozone and S3
