[pyup-bot]

This PR updates pylint from 2.5.3 to 2.6.0.

Changelog

2.6.0

===========================

Release date: 2020-08-20

* Fix various scope-related bugs in ``undefined-variable`` checker

Close 1082, 3434, 3461

* bad-continuation and bad-whitespace have been removed, black or another formatter can help you with this better than Pylint

Close 246, 289, 638, 747, 1148, 1179, 1943, 2041, 2301, 2304, 2944, 3565

* The no-space-check option has been removed. It's no longer possible to consider empty line like a `trailing-whitespace` by using clever options

Close 1368

* ``missing-kwoa`` is no longer emitted when dealing with overload functions

Close 3655

* mixed-indentation has been removed, it is no longer useful since TabError is included directly in python3

Close 2984 3573

* Add `super-with-arguments` check for flagging instances of Python 2 style super calls.

* Add an faq detailing which messages to disable to avoid duplicates w/ other popular linters

* Fix superfluous-parens false-positive for the walrus operator

Close 3383

* Fix `fail-under` not accepting floats

* Fix a bug with `ignore-docstrings` ignoring all lines in a module

* Fix `pre-commit` config that could lead to undetected duplicate lines of code

* Fix a crash in parallel mode when the module's filepath is not set

Close 3564

* Add `raise-missing-from` check for exceptions that should have a cause.

* Support both isort 4 and isort 5. If you have pinned isort 4 in your projet requirements, nothing changes. If you use isort 5, though, note that the `known-standard-library` option is not interpreted the same in isort 4 and isort 5 (see the migration guide in isort documentation for further details). For compatibility's sake for most pylint users, the `known-standard-library` option in pylint now maps to `extra-standard-library` in isort 5. If you really want what `known-standard-library` now means in isort 5, you must disable the `wrong-import-order` check in pylint and run isort manually with a proper isort configuration file.

Close 3722

2.5.4

===========================

* Fix a crash caused by not guarding against `InferenceError` when calling `infer_call_result`

Close 3690

* Fix a crash in parallel mode when the module's filepath is not set

Close 3564
