refactor: Standardize body parameter names

[alexandear]

This PR adds the requestbody custom linter to simplify code review. Changes are non-breaking.

The requestbody does the following:

• suggests renaming a body parameter to body
• reports body parameters passed by pointer, because body parameters are usually required
• reports body parameter types with an Options suffix, because Options are used for query parameters

I'm wondering if we should standardize on an "Options" suffix for query (URL) parameters at the same time since we are standardizing on a "Request" suffix for body parameters?

If so, it seems to me like this new linter is the perfect place to put this.

Thoughts?

Agree, good idea. I'll extend the linter.
Also should think of a better name for the linter.
