* no self in this code
* Two fixes:
- fix run_command execution, passing 'use_unsafe_shell=True' since we have a pipe in it ( | grep )
if we don't set unsafe shell, it will return error on execution.
- strip new line characters at the end of WWNs.
* fix pep8 , E225 missing whitespace around operator
* use module.get_bin_path() instead of hardcoded values
* move module.get_bin_path() out of for loop
* use python string parsing instead of calling external grep
* use in operator instead of find() for simplicity and readability
* add changelog fragment
