Missing ArgumentError for undeclared keyword args

[scottgratton]

ActiveInteraction is awesome and has become a fundamental tool for my engineering team - so, first, thanks!

I'd like to propose (unless it already exists and I'm missing it) some kind of option to allow an ActiveInteraction object to raise an ArgumentError much like a Rails method given an unexpected keyword argument. In many simple cases, it's probably easy enough to search through usages in the code base and check, but I've seen arguments continue to get passed to a service object after they've been removed from the service, or typos where there just wasn't a test asserting the change expected from the given argument. Knowing that ActiveInteraction would flag these unexpected arguments would be helpful for maintaining services over the course of time.

To illustrate the difference, here is an example of a basic Rails method and a basic ActiveInteraction service and the behaviors:

def my_method(foo:)
  # whatever
end

my_method(foo: 'bar', something_unexpected: 'baz')
# => ArgumentError: unknown keyword: :something_unexpected

class MyActiveInteractionService < ActiveInteraction::Base
  string :foo

  def execute
    # whatever
  end
end

MyActiveInteractionService.run!(foo: 'bar', something_unexpected: 'baz')
# => nil

Thanks in advance to any who weigh in on this 🙏
