Improve the way of passing args down to underlying tools

[sbekrin]

🚀 Feature Proposal

Motivation

Currently all commands requires -- to indicate that we want to pass arguments to underlying tools they execute. Although it's a common pattern, it adds a bit of mental complexity to remember to always add those. It also doesn't play nicely with yarn, which cuts first -- and as result requires using something like spire lint -- -- --fix.

Example

Current way:

spire lint --debug -- --fix

Proposed way:

spire --debug lint --fix
