More template stuff (#2164)

- Configure now asks for the users knowledge level, so advanced mode can be reached without calling with `--advanced`
- Add template for solaredge inverter
- Add beta template for sungrow inverter
- Add template for MQTT based meter
- Add more template documentation
- Add check and error message for invalid config properties when using templates
- Option to specify language specific template descriptions
- Option to make params dependent on values of other params 
- Option to add sponsortoken in advanced mode
- Option to set minCurrent in advanced mode
- Remove sponsorship requirement from Daheimladen wallbox
- Multiple fixes (FritzDect meter, Kostsal Piko meter, ...)
