Verbose should not enable debug level logging
Verbose should not enable debug level logging

Fixes LP #989269

Currently setting --verbose in will still allow DEBUG level
message to be logged to python logger object. we need to check
for --debug first (set DEBUG level), then --verbose (set INFO
level) and if neither is set then set default to WARNING
