Extensions to integration

[aschamberger]

• added additional infos regarding regeneration agent usage and number of regenerations
• added German translation
• added methods to api.py that are not used yet
  • extracting additional infos from HTML: get_warnings() + get_holiday_mode()
  • added save_value() to trigger holiday_mode, extra cleaning and extra regeneration

idea was to add the following (which proved to go beyond my python/home assistant skills):

• Switch Entity: Vacation Mode on/off --> get_holiday_mode() + save_value(484,1)/save_value(484,0)
• Button Entities: Start Extra Regeneration --> save_value(482,1) and Start Extra Cleaning --> save_value(483,1)

Wow, great work, i can handle switch part or can show you how to do it?

Thanks. Would be great if you can add the switch (and button entities). Maybe I can learn from that and do sth. with the messages afterwards...
