Provide a --ignore-file option with .gitignore as default

[soullivaneuh]

Current problem

When I run pylint, report warning are found on files ignored by .gitignore (vendor, generated file etc...).

Because of that, I have to specify nearly the same configuration as the .gitignore to the --ignore-paths option, but with a different format.

This is config repetition that make project and CI configuration heavier to maintain.

Desired solution

Make pylint considering the .gitignore file for analysis ignorance.

it SHOULD also provide a --ignore-file option to specify an another file than .gitignore to consider.

It MAY also taking into account equivalent of .gitignore for other versioning tools (svn, hg...).
