Cloud control support (and firmware 2.7)

Hi all. I completely rewrote a component to support management both local and cloud control at the same time.

Why I added cloud support?

• devices with 2nd firmware do not support the latest API of LAN control
• so many users have problems setting up multicast traffic
• some users have problems with multiple routers
• some users have devices in other locations
• for some users, the router freezes from multicast traffic
• after rebooting HA, devices do not always appear immediately (unavailable problem)
• devices may sometimes not respond to a local command (can't send switch to problem)

If you want me to add support for your device: share it through the eWeLink mobile application to my account [e-mail]

Waiting for feedback from you.

@AlexxIT yes confirmed, i updated to latest master component and all sensors were loaded as sensors, thanks Alex for your amazing work 😃

For now it looks great, I restarted HA a couple of times and both my Sonoff devices are available and responding immediately after boot. Also the Log problem described in issue #97 is gone… well, not really gone but it’s not tied to Sonoff anymore, now it reads

2020-05-11 14:14:55 WARNING (zeroconf-ServiceBrowser__axis-video._tcp.local.) [zeroconf] Exception occurred:
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/zeroconf/__init__.py", line 2644, in send
    bytes_sent = s.sendto(packet, 0, (real_addr, port))
OSError: [Errno 126] No error information

So it might have not been directly related to Sonoff after all… Will keep monitoring and report if troubles occur.
