Raise exception on not-implemented @setting(setter)

[starkillerOG]

Split out from #1586
warn for setter input from setting decorator, since it will not work to put in a function directly in the decorator since the class object has not yet been created. Therefore always the setter_name schould be used and the binding of the setter methods schould take place when the class object gets created.

@rytilahti ready to be merged.

Can be merged after the linting issue is fixed.

[starkillerOG]

@rytilahti I think the linting issue is resolved.
No idea why my tests are beeing so flaiky.

I am calling it a day, will continue tommorow.
Thanks for the help and quick response today!

[rytilahti]

Hehe, my pleasure, have a good one! Looks like we were quite productive with short feedback cycles :-)

The CI flakiness is something that has happened before and I thought using the codecov token would help, but this time you were also encountering this issues: #1580 - the tests will suddenly start working in 30 mins...
