Feature: find extra parentheses that can be removed

[sobolevn]

Rule request

Thesis

There are cases when parentheses can be removed. Like: x = ('string'). There are also examples when it can not be removed: x = (1 + 3) * 2

There are also cases when they should not be removed (since I prefer to use tuple with explicit parentheses): x = (1, 2).

Reasoning

This will increase consistency.

Format

This should be a separate plugin. Because I am sure that this will be impossible to achieve without logical_line param. Related: https://rules.sonarsource.com/python/RSPEC-1110
