Allow setting PYLINT_HOME via pyproject.toml

[woutervh]

Current problem

PYLINTHOME is actually cache-dir, but you can only set it via an environment-variable:

export PYLINTHOME="<path-to-project_dir>/var/cache/pylint"

while other tools like pytest and mypy allow to set their cache-dir in pyproject.toml like this:

[tool.mypy]
cache_dir = "var/cache/mypy"

[tool.pytest.ini_options]
cache_dir = "var/cache/pytest"

Desired solution

It would be nice if pylint could support something similar:

[tool.pylint]
pylint_home = "var/cache/pylint"

I want the same thing actually. it'll make my life easier and less files floating around and every config files just in pyproject.toml and done with it
