[Feature] Make Vacation period ("Urlaub" in german app) available

[ghenzler]

The app provides the functionality to set a period for a vacation time... during this time the power consumption is the lowest possible (even better than when on standby for some reason, measured it with a shelly). It's a simple setting of start date and end date in the APP (my experience shows that it's heating up during end date already to ensure a warm house after vacation).

I think this should be fairly easy to implement as it is just setting two dates (maybe via home assistant service call?).

This seems doable. Will look at the API to see.
