Controllers should better leverage args structs

[julianKatz]

Both the node and controller instantiations have method signatures with 8+ arguments. Let's make use of structs of args to make these signatures cleaner.

Hi @julianKatz, can you please elaborate this more ?

See these references to the issue in the codebase

Both the node and controller structs have very long constructors. Now that args structs have been created, we could simplify things a bit by using those.
