feat: add optional args to each command

[OlegChuev]

Added optional args as a variadic param. Not sure if it's better to use it as it is or move to the Options struct

I'd prefer it as part of the Option struct so we don't change the function signatures. Would you be willing to make that change or should I?

Sure, I'll take a look shortly. Thanks for the feedback!
