Django-pylint dependency not needed

Currently there is a dependency with the pylint django and flask dependencies that are not needed for the dev environment.

We should keep out those dependencies

I believe that prospector install all dependencies automatically

@Virako please verify the state of this issue. If it is not needed I'd remove the dependency, otherwise, close the issue

This dependency only appears on dev enviroment. Its included because of the use of prospector
