Subject: [PATCH] Add Fujitsu FGLair integration (#109335)

* Add support for Fujitsu HVAC devices

* Add the entity code to .coveragerc

* Only include code that can fail in the try/except block

Co-authored-by: Josef Zweck <24647999+zweckj@users.noreply.github.com>

* Remove empty keys from manifest

* Remove VERSION as it's already the default

* Remve the get_devices function and use asyncio.gather to parallelize dev updates

* Move initial step to a function

* Let KeyError bubble up. If we are passed an invalid mode it's probably worth raising an exception.

* Await the gather

* Use the async version of the refresh_auth call

* Use the serial number as unique id

* Use HA constant for precision

* Use dev instead of self._dev

* Move to property decorated methods

* Remove bidict dependency

* Setup one config entry for our api credentials instead of per device

* Remove bidict from requirements

* Signout and remove our api object on unload

* Use app credentials from ayla_iot_unofficial

* Use entry_id as a key to store our API object

* Delete unused code

* Create reverse mappings from forward mapping instead of hardcoding them

* Clean up the property methods

* Only import part of config_entries we are using

* Implement suggested changes

* Fix tests to use new API consts

* Add support for reauth

* Use a coordinator instead of doing per-entity refresh

* Auto is equivalent to HEAT_COOL not AUTO

* Add ON and OFF to list of supported features

* Use the mock_setup_entry fixture for the reauth tests

* Parametrize testing of config flow exceptions

* Only wrap fallable code in try/except

* Add tests for coordinator

* Use self.coordinator_context instead of self._dev.device_serial_number

* Move timeout to ayla_iot_unofficial

* Add description for is_europe field

* Bump version of ayla-iot-unofficial

* Remove turn_on/turn_off warning

* Move coordinator creating to __init__

* Add the type of coordinator to the CoordiatorEntity

* Update docstring for FujitsuHVACDevice constructor

* Fix missed self._dev to dev

* Abort instead of showing the form again with an error when usernames are different

* Remove useless argument

* Fix tests

* Implement some suggestions

* Use a device property the maps to the coordinator data

* Fix api sign out when unloading the entry

* Address comments

* Fix device lookup

* Move API sign in to coordinator setup

* Get rid of FujitsuHVACConfigData

* Fix async_setup_entry signature

* Fix mock_ayla_api

* Cleanup common errors

* Add test to check that re adding the same account fails

* Also patch new_ayla_api in __init__.py

* Create a fixture to generate test devices

* Add a setup_integration function that does the setup for a mock config entry

* Rework unit tests for the coordinator

* Fix typos

* Use hass session

* Rework reauth config flow to only modify password

* Update name to be more use-friendly

* Fix wrong type for entry in async_unload_entry

* Let TimeoutError bubble up as teh base class handles it

* Make the mock ayla api return some devices by default

* Move test to test_climate.py

* Move tests to test_init.py

* Remove reauth flow

* Remove useless mock setup

* Make our mock devices look real

* Fix tests

* Rename fujitsu_hvac to fujitsu_fglair and rename the integration to FGLair

* Add the Fujitsu brand

* Add a helper function to generate an entity_id from a device

* Use entity_id to remove hardcoded entity ids

* Add a test to increase code coverage
