Newer versions of pylint will now check your code as you type. Older
versions will still only check the file on disk.

Pylint only [checks for pylintrc] (and .pylintrc) files in the packages
aboves its current directory before falling back to user and global
pylintrc. For projects with a src dir, running pylint from the
directory containing the file will not use the project pylintrc.
Adopt the convention used by many other Python linters of running from
the project root, which solves this issue. Add pylintrc and .pylintrc
to FindProjectRoot. Update docs.

When set to true, and the buffer is currently inside a pipenv,
GetExecutable will return "pipenv", which will trigger the existing
functionality to append the correct pipenv arguments to run each linter.
Defaults to false.
I was going to implement ale#python#PipenvPresent by invoking
`pipenv --venv` or `pipenv --where`, but it seemed to be abominably
slow, even to the point where the test suite wasn't even finishing
("Tried to run tests 3 times"). The diff is:

Using vim's `findfile` is much faster, behaves correctly in the majority
of situations, and also works reliably when the `pipenv` command doesn't
exist.
