* Add support for passive devices

* Fix a few issues

* Fix broken handling of closing a connection

This fixes the following error:

  AttributeError: 'NoneType' object has no attribute 'write'

* Always use discovery broadcasts to trigger connects

From now on there's no connect loop but all attempts are initiated by
received discovery messages.

* Fix cancelling of heartbeat task

* Verify entry has been loaded before connecting

* Don't reset seqno when switching to type_d device

Forgot to add an await to the close method in pytuya when validating the
device. This results in the connection never being closed after adding a
device, giving "connection resets" until the connection fails, the
device or Home Assistant is restarted.

Fix one more HA scene problem

Use debug message for timeout.

* Make connection retries every minute

This mimics the re-connect loop previosuly present, but in a simpler
form. Every 60 seconds, a new connection attempt is made as well as
initially when a device is set up.
