[REQ] Disable clippy::too_many_arguments in generated Rust client code.

[maxnachlinger]

Is your feature request related to a problem? Please describe.

Generated Rust clients often contain functions with > 7 args which violates the Rust clippy too_many_arguments rule.

Describe the solution you'd like

We can simply ignore this rule in generated code via:

#![allow(clippy::too_many_arguments)]

Describe alternatives you've considered

An alternative would be to refactor the client generation to provide an input struct.
