Feature Request: state_check_now kwarg for state_trigger

[dlashua]

I use this pattern often:

@state_trigger((
    "float(sensor.master_temperature) <= float(climate.hvac_up.temperature)"
    " and input_select.master_mode == 'sleep'"
))
def turn_on_heater():
    log.info('Turning on Heater')
    switch.turn_on(entity_id="switch.master_heater")

The issue is, I'd also like that same check to be performed at startup (i.e. when the trigger is registered). I can't just use @time_trigger('startup') because the conditions in the state_trigger won't be checked. I can't just change @state_trigger to @state_active because then it'll ONLY trigger at startup. So, instead, to accomplish what I want, I have to have a state_trigger, a time_trigger, and a state_active.

Adding state_check_now to @state_trigger would allow me to keep the code short and reduce redundancy.
