Get rid of documentation warnings - make documentation work for interfaces

[mattuntergassmair]

Using julia --project make.jl prints several warnings for missing docstrings, for example for the get_name function. get_name is documented in the interface, but without argument signature. The documentation (such as in docs/src/behaviors.md) currently lists get_name(::DriverModel for documentation which creates a warning.

More generally, the goal should be to make the documentation-generation warning-free

I agree with this.

Regarding get_name specifically, it should be deprecated now so we can remove it from the doc.
