Add support for automatic discovery of TP-Link switches, bulbs and dimmers (#18091)

* {switch,light}.tplink: use deviceid as unique id, fetch name from the device during initialization

* raise PlatformNotReady when no device is available

* Use mac instead of deviceid

* remove name option as obsolete

* Add support for configuration flow / integration

Allows activating automatic discovery of supported devices from the configuration

* Fix linting, update requirements_all.txt

* start cleaning up tplink component based on feedback

* add device info, improve config handling

* Allow overriding detected devices via configuration file

* Update requirements.txt

* Remove debug logging

* make hound happy

* Avoid I/O during init and simplify the code, remove remains of leds_on

* Fix issues based on feedback, use consistent quotation marks for device info

* add async_setup_platform emiting a deprecation warning

* Avoid blocking the I/O, check for None on features

* handle some Martin's comments, schema-validation is still missing

* use async_create_task instead of async_add_job, let core validate the schema

* simplify configuration handling by storing the configuration data separately from initialized instances

* add default values to schema, make hound happy

* with defaults set by schema, simplify the checks. add async_unload_entry

* Use constant for data structure access

* REWORD add a short note about async_unload_entry

* handle feedback from Martin, config_data is checked against Noneness

* use pop to remove the domain on unload

* First steps to add tests for the new tplink component

* embed platforms under the component directory

* Fix tests by mocking the pyhs100 internals

* Fix linting

* Test against multiple instances of devices, tidy up

* (hopefully) final linting round

* Add pyHS100 to test requirements

* log always the warnings occured during an update to make them easy to see

* revert back the warning behavior (requirement for silver level in IQS)

* Unload only when an entry is being loaded and add tests for that

Thanks @MartinHjelmare for pointing this out!

* Fix linting

* Bump the upstream lib, fixes most prominently the HSV setting on bulbs

* Test unloading for all platforms, clear the data storage instead of popping it out, making it possible to reconfigure after removal without restarting hass first

* Use class variables instead of instance variables for bulb states, required for HS220

* Use new-style format string

* Fix indenting, uppercase the mock constant

* Run black on test_init, hopefully that will finally fix the weird formatting (pycharm, pylint and hound seems to have different opinions...)
