HASSIO example revisions

[ktownsend-personal]

I sync'd the HASSIO config example to match what I have done on my system.

Summary of changes:

• a few /enabled topic fixes
• fixed the reversed payload_on & payload_off for the freeze protection switch
• added icons where possible
• added delay binary sensors
• added delay attribute on related switches
• added active attribute on related heater switches
• added device_type where possible
• changed the custom battery sensor to a simulated level sensor because it's useful for battery lists in the UI, and the OK/LOW custom sensor became obsolete when I gave the mqtt binary sensor a device_type of battery (it now reports Normal/Low)
• removed the groups because I didn't find any use for them in my situation
• moved the pool & spa lights to switch instead of light to be more consistent with the Home Assistant convention of light being a dimmable device and non-dimmable lights being switch devices
• added a custom service mode sensor to give the 3 states some readable labels: AUTO, SERVICE, TIMEOUT
• added an automation to turn off the heaters when the filter pump shuts off so the heaters aren't on the next day if someone forgot to shut them off

The link in your wiki to this file is misspelled and doesn't match the casing, so it's a broken link. I can't do a PR for the wiki, otherwise I'd fix it for you :)

Oh, I should mention I'm edge9421 on your forum, since my name is different here.
