Add ecobee ventilator 20 min timer

[marcolivierarsenault]

Proposed change

Add ventilator 20 min timer switch. To replicate a feature of the physical device (Ecobee).

This option starts a 20 min timer for the ventilator. The ventilator will run for 20 min and the stop.

This requires to add a new Platform (Switch) that was not use yet in this integration.

Sadly the API of Ecobee is not ideal, to detect if the switch is on you have to look if the ventilatorOffDateTime is in the future.
To get the correct time, we need the timezone info from the thermostat. An update of the underlying library connecting to Ecobee was required:

• nkgilley/python-ecobee-api@0.2.17...0.2.18

To turn it on or off, we have to reset the value of set_ventilator_timer

Just for context I am trying to mimic the real device behaviour

As you can see the ventilator is running. (Because of min ventilator setting)

But the 20 min switch is off

The 20 min switch is what I am trying to go here

@PeteRager @joostlek just updated the code to remove the part that was an anti-pattern.

Note the behaviours are exactly the same. Switch works like extended
