[REQ] request middleware for Zapier generator.

[a-wallen]

Is your feature request related to a problem? Please describe.

APIs that use some form of session auth, whether it be API keys or basic auth that requires parameters other than a Bearer token do not have support with the current generator.

In order to support this, there needs to be middleware that can include these request options.

Describe the solution you'd like

utils.js should include a request middlware
