Add support for Ecobee Switch+

[niemyjski]

The following shows off how to get access to a list of all switches via polling

I Found that logging into your Ecobee account it makes a request to https://api.ecobee.com/ea/devices/ls?format=json to pull for changes and get a list of all devices with identifiers and full metadata..

Then when you make a state change like turn on or off it makes a PATCH https://api.ecobee.com/ea/devices/ls/ID_HERE?format=json with the state {"state":{"on":true}}.

@nkgilley would you be willing to pair on this?
