Added setDomesticHotWaterSchedule command for Heating Devices

Added setDomesticHotWaterSchedule command for Heating Devices. Tested with V200KW1.

It's been a while and i'd really like to see this command available. Any news on this PR?

[CFenner]

Thanks for the PR, could you add types to the function and parameters. Also tests would be nice.

Here's what CFenner is asking for:

Type annotations:

@handleAPICommandErrors
def setDomesticHotWaterSchedule(self, schedule: dict):
    return self.service.setProperty("heating.dhw.schedule", "setSchedule",
                                    {'newSchedule': schedule})

Test (e.g., in test_Vitocal200.py which has the setSchedule command):

def test_getDomesticHotWaterScheduleModes(self):
    expected_modes = ['on']  # check your test data for actual modes
    self.assertSetEqual(
        set(self.device.getDomesticHotWaterScheduleModes()), expected_modes)

You might also want to add getDomesticHotWaterScheduleModes() to retrieve available modes, following the pattern of getDomesticHotWaterCirculationScheduleModes().
