API Key Authentication applies to documentation too

[kellersyf]

Context

When I enable API Key Authentication, the API is authenticated as expected. Unfortunately, the docs are also authenticated. Since I can't (without extensions) add the API key to the header for my browser, I can't see the docs.

Expected Behavior

I should be able to browse docs without an API key.

Actual Behavior

Everything is authenticated including the docs.

Possible Fix

If this is intended, add an option to authenticate (or not) documentation.

Steps to Reproduce

1. Create a project with api_key_required = true
2. Deploy project
3. Browse to the API Gateway URL for documentation using any web browser without special settings to change header.
4. Receive "Forbidden" response.
