Tesla platform (#9211)

* Tesla support implemetation

* requirements_all.txt fix

* .coveragerc fix

* logging-too-many-args fix

* logging-too-many-args attempt 2

* Post-review fixes.

* requirements version fix

* requirements

* Lint fix

* Hot fix

* requirements_all.txt fix

* Review preparation.

* 1. Linting fix.
2. Minimal value for SCAN_INTERVAL hardcoded to 300 sec (to prevent possible ban form Tesla)

* Removed redundant whitespace.

* Fixed components according to @MartinHjelmare proposals and remarks.

* .coveragerc as @MartinHjelmare suggested.

* Minor changes

* Fix docstrings

* Update ordering

* Update quotes

* Minor changes

* Update quotes
