* Extract mysensors name function.
* Add setup_mysensors_platform for mysensors platforms.
* Add mysensors const schemas.
* Update mysensors callback and add child validation.
* Remove gateway wrapper class.
* Add better logging for mysensors callback.

* Remove discovery in mysensors component setup.
* Clean up gateway storage in hass.data.
* Update all mysensors platforms.
* Add repr for MySensorsNotificationDevice.
* Fix bug in mysensors climate target temperatures.
* Clean up platforms. Child validation simplifies assumptions in
platforms.
* Remove not needed try except statements. All messages are validated
already in pymysensors.
* Clean up logging.

* Use discovery to set up mysensors notify platform.
* Add discovery_info to get_service and update tests
* Add discovery_info as keyword argument to the get_service function
signature and update all notify platforms.
* Update existing notify tests to check config validation using test
helper.
* Add removed tests back in that checked config in apns, command_line
and file platforms, but use config validation test helper to verify
config.
