rabbah opened a new pull request #3627: remove unused imports or dead variables as reported in travis build.
URL: https://github.com/apache/incubator-openwhisk/pull/3627
 
 
   I noticed in travis builds there are several python related warnings from the flake8 - so I removed them.
   
   ```
   /tests/dat/actions/sleep.py:12:1: F401 'sys' imported but unused
   ./performance/gatling_tests/src/gatling/resources/data/pythonAction.py:4:1: F401 'sys' imported but unused
   ./actionRuntimes/actionProxy/invoke.py:39:1: F401 'traceback' imported but unused
   3     F401 'traceback' imported but unused
   ./tools/admin/wskadmin:534:5: F841 local variable 'argsDict' is assigned to but never used
   ./tools/admin/wskadmin:553:5: F841 local variable 'argsDict' is assigned to but never used
   2     F841 local variable 'argsDict' is assigned to but never used
   ```
