PR: Pass paths from the Pythonpath manager to the Pylint plugin

[znapy]

Description of Changes

Add the PYTHONPATH environment from pythonpath-manager to the pylint plugin to access the root of the project without packages.

Example:

Suppose, you have a project with a single script (for simplicity in a spyder environment):

my-project
| - do_something.py

and you write a test:

my-project
| - do_something.py
| - tests
  | - test_do_something.py

In test_do_something.py you access to import do_something. So if you start Source -> Run code analysis it will show the error Unable to import 'do_something'. But in the IPython console !pylint tests/test_do_something.py doesn't show this error because there is PYTHONPATH environment.

And you should take additional steps to solve this problem, for example, make a packages:

my-project
| - my_project
  | - __init__.py
  | - do_something.py
  | - tests
    | - __init__.py
    | - test_do_something.py

or fix paths in pylintrc or pyproject.toml (section [tool.pylint], value init-hook=...):

my-project
| - do_something.py
| - tests
  | - test_do_something.py
| - pyproject.toml

No hacks are needed with this PR - it works out of the box.

Thanks for your contribution @znapy! I think this is really good improvement.

I left several suggestions for you to fix minor code style issues here and there to start with.

In case you haven't used Github reviews before, you can submit all those suggestions in a single commit by adding them to the batch, as described here.

Also, so sorry for not paying attention to your work before. We were busy preparing things for Spyder 6.0 and missed your PR. But we'll try to merge it for 6.1, to be released in a few months.

Thanks for the update @znapy! Overall your changes look good to me and our tests are passing, which is good too.

@dalthviz, could you give this a manual check, following @znapy OP, to see if you get the expected behavior? Thanks!
