* HBASE-24806 Small Updates to Functionality of Shell IRB Workspace
- Move exception handler from Shell::Shell#eval_io to new method,
Shell::Shell#exception_handler
- Add unit tests for Shell::Shell#exception_handler
- Change Shell::Shell#eval_io to no longer raise SystemExit when any error is
seen and update unit test
- Update ruby test runner to catch SystemExit and fail to avoid tests that
cause the test runner to incorrectly exit successfully
- Add Hbase::Loader module to find ruby scripts in the $LOAD_PATH and classpath
using JRuby's loader.
- In hbase-shell, install IRB commands before exporting HBase commands. The
HBase commands will override the IRB commands, and no warning will be
printed.
* Remove unused variables from shell_test
