PEP8 MR5 E5xx: line length

I am trying to make Samba Python code follow PEP8 code style with autopep8.

To avoid making monster commit, I will make MR by Error Code groups.

This Merge Request is based on PEP8 MR4 E4xx: import

It includes the fixes from autopep8 for line length(error codes E5xx), although E501: line too long is ignored because we have too many violations.

Following MRs are coming based on this one.
