Do not camelcase options

[mrlubos]

Describe the problem

We do not camelcase each key in requestBody, but we camelcase parent keys (e.g. path parameters). This is inconsistent and creates unnecessary complexity. In the end, we cannot avoid working with snake case values.

Describe the proposed solution

Instead of what we have today

MyService.operationFoo({
  requestBody: {
    foo_bar: ''
  },
  bazQux: ''
})

this should become

MyService.operationFoo({
  requestBody: {
    foo_bar: ''
  },
  baz_qux: ''
})

We will need a codemod to migrate existing clients
