Tony Murray 3e35ee0e7d Refactored and update Location Geocoding (#9359)
- Fix location so it is a regular database relation (this allows multiple devices to be accurately linked to one location and saves api calls)
- Parse coordinates from the location more consistently
- Add settings to webui
- ~~Used [PHP Geocoder](http://geocoder-php.org/), which has lots of backends and is well tested. (also includes reverse and geoip)~~
- Google Maps, Bing, Mapquest, and OpenStreetMap supported initially.
- Default to OpenStreetMap, which doesn't require a key.  They will liberally hand out bans if you exceed 1 query per second though.
- All other Geocoding APIs require an API key. (Google requires a credit card on file, but seems to be the most accurate)
- Update all (I think) sql queries to handle the new structure
- Remove final vestiges of override_sysLocation as a device attribute
- Update existing device groups and rules in DB
- Tested all APIs with good/bad location, no/bad/good key, and no connection.
- Cannot fix advanced queries that use location
