add support for grouping by message, not just filename

[sandrotosi]

Is your feature request related to a problem? Please describe.
when first introducing pylint on an established codebase, it will produce several messages, and currently the pycharm plugin groups them by file, f.e.:

• fileA.py
  • msg1
  • msg2
  • msg3
• fileB.py
  • msg3
• fileC.py
  • msg2

Describe the solution you'd like
but when tackling several different types of messages, sometimes it would be more convenient if the output is organized like:

• msg1
  • fileA.py
• msg2
  • fileA.py
  • fileC.py
• msg3
  • fileA.py
  • fileB.py

the reason being that a certain message most likely have a similar resolution among different files

Describe alternatives you've considered
none

Additional context

Hi @sandrotosi ,

A new developer, @szabope, has created a full rewrite of this PyLint plugin. The new plugin is actively maintained and addresses many of the issues found here.

You can find the new plugin on the JetBrains Plugin Marketplace: PyLint Plugin
The source code is available here: GitHub Repository

This plugin is going to be decommissioned soon so it's probably better to request this new feature there.
