New sensors for mobileStart, energy/water forecast, drying step, program phase, spin speed, battery level + New services to start/end programs

[aturri]

• Move capabilities into init.py
• Split eco feedback capability into water and energy (e.g. tumble dryer class does not need water consumption sensor)
• Split target temperature capability for washer, washer-dryer and dishwasher in order to have a single temperature sensor (other 2 temperatures are used for ovens or fridges) and give result as integer
• Condition signalInfo, signalDoor, signalFailure to device capability according to Miele specs
• Expose mobileStart binary sensor (e.g. to allow starting programs or starting coffee)
• Expose services to start and stop programs (together with mobileStart sensor it is possible to implement Wash2Dry feature with an automation that picks program from washer and selects it on the dryer)
• Expose drying step, program phase, spin speed, battery level sensors
• Expose energy and water forecast sensors
• Fix consumption and time sensor to provide cached value when appliance disconnects from Miele cloud (could mess up stats and automations based on appliance remaining time)
