Support for Xiaomi Aqara single key wireless wall switch about domoticz-zigbee2mqtt-plugin HOT 2 CLOSED

I start creating support for this device, can you please check and give feedback. When you think the implementation is correct, please merge.

1. added in plugin.py
   from adapters.lumi.sensor_86sw1 import Sensor86Sw1
   and into the self.adapter_by_model = { part
   'WXKG03LM': Sensor86Sw1, # Xiaomi Aqara single key wireless wall switch

2. add a new device push_on_button.py in the devices folder with the code

import Domoticz
from devices.device import Device
class PushOnButton(Device):
    def create_device(self, unit, device_id, device_name, message):
        return Domoticz.Device(Unit=unit, DeviceID=device_id, Name=device_name, Type=244, subtype=73, Switchtype=9).Create()
    def get_numeric_value(self, value, device):
        return 1 if value.lower() == 'single' else 0
    def get_string_value(self, value, device):
        return 'On' if value.lower() == 'single' else 'Off'

3. add a new adapter sensor_86sw1.py in teh adapters/lumi folder with the code

import Domoticz
from adapters.base_adapter import Adapter
from devices.push_on_button import PushOnButton

class Sensor86Sw1(Adapter):
    def __init__(self, devices):
        super().__init__(devices)
        self.devices.append(PushOnButton(devices, 'switch', 'click'))

This will create a switch of the sub-type Push On Button.
I found one strang behavior, the off-delay of this created devices is not working.
In the log, I only see on values
When I created the same type by a dummy-hardware, the off-delay is working?
