Upgrade pylint to 1.8.2 (#12274)

* Upgrade pylint to 1.8.1

* Fix no-else-return

* Fix bad-whitespace

* Fix too-many-nested-blocks

* Fix raising-format-tuple

See https://github.com/PyCQA/pylint/blob/master/doc/whatsnew/1.8.rst

* Fix len-as-condition

* Fix logging-not-lazy

Not sure about that TEMP_CELSIUS though, but internally it's probably just like if you concatenated any other (variable) string

* Fix stop-iteration-return

* Fix useless-super-delegation

* Fix trailing-comma-tuple

Both of these seem to simply be bugs:
 * Nest: The value of self._humidity never seems to be used anywhere
 * Dovado: The called API method seems to expect a "normal" number

* Fix redefined-argument-from-local

* Fix consider-using-enumerate

* Fix wrong-import-order

* Fix arguments-differ

* Fix missed no-else-return

* Fix no-member and related

* Fix signatures-differ

* Revert "Upgrade pylint to 1.8.1"

This reverts commit af78aa00f125a7d34add97b9d50c14db48412211.

* Fix arguments-differ

* except for device_tracker

* Cleanup

* Fix test using positional argument

* Fix line too long

I forgot to run flake8 - shame on me... 🙃

* Fix bad-option-value for 1.6.5

* Fix arguments-differ for device_tracker

* Upgrade pylint to 1.8.2

* 👕 Fix missed no-member
