IMPALA-12470: Support different schemes for jdbc driver url when
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
