Changelist

[saladas3]

• Add possibility to create epics on groups on gitlab
• Try to improve code readability by respecting PEP 8 standard
• Fix an issue with attachments extensions and them being downloaded from a wrong path from gitlab
• Add 2 more configuration flags in jira2gitlab_config.py
• Commented the contents of file jira-user-list.py as it was not used anywhere to avoid confusion

I hope the changes are of use. There could be errors in the process_links function for the epic issues created, not sure.

@saladas3 thank you for sharing these contributions.

Most likely I'm going to integrate the important parts (epics, fix on the attachments and most of the small overall fixes), but not minor things like using double quotes or commenting the entire jira-user-list.py script (maybe I'll move it to a separate folder)..

I probably won't be able to to this soon though, also because the change on epics and its impact on the links and import state needs to be checked carefully.
