feat: Allow unverified openapi calls

[richardpaulhudson]

Proposed Changes:

With the existing code, there is no way of disabling SSL verification for OpenAPI function calls. This PR fixes this by introducing an optional initialization parameter that corresponds exactly to the openapi3 initialization parameter and that is fed through to it.

How did you test it?

I ran and fixed the unit tests and also confirmed that the fix works as intended with my own client code.

Notes for the reviewer

This page will need updating, but I was unsure how to do so to make the documentation change sync with the code change.
