Change action of sprinkler.start_full_cycle in Sprinkler Controller

** In the Sprinkler Controller if no valves are enabled and you call sprinkler.start_full_cycle action then the controller will enable all values and run a full cycle. Would like this to be optional as there are use cases where all vales are disabled and the sprinkler.start_full_cycle could be called.**

**Valves could be enabled and disabled by Home Assistant automations based on weather condition, previous and forecast rain amounts, soil moisture levels, etc. There could be a situation where all valves have be disabled based on the above conditions and if the sprinkler.start_full_cycle is called as part of a schedule then all the valves will run there normal program but really you wanted none to run.**

** This could be an _(optional, String)_ like the other switches in the sprinkler controller and default to ON so as not to affect previous versions.**
