Correctly handle required query params in CLI generation (#2027)

## Changes
If there's required query params, it is a top-level field of request
object and not a field of nested request body.

This is needed for upcoming changes from OpenAPI spec changes where such
query parameters is introduced.

No changes after regenerating CLI with current spec and the fix (appears
we haven't had such params before)
