Breaking change: mDNS is (no longer) required

[andig]

With 0.210.0 we've simplified configuration of HomeAssistant devices. With this change, uri and token are no longer supported. Instead, HomeAssistant instances are configured using their home name as announced over mDNS. The default home name is Home:

However, this will only work if the HomeAssistant instance can be detected ver mDNS. If the dropdown list is empty, mDNS is not working and needs be fixed.

Docker users

For mDNS make sure that:

• evcc has access to 5353/udp
• potentially use host networking
• or use an mDNS redirector to relay the mDNS broadcasts to a docker network
