SafeLinx http-service: Exempt URL paths from Authentication

The Let's Encrypt servers need access to `/.well-known/acme-challenge/<TOKEN>` without authentication

For HCL Connections external user registration and password reset, users need to access the WAS server without authenticating first.

Current workaround here is to use a separate Domain/http-service for the Invite functionality.

In both cases, we would need to exclude specific URL paths in the http-service from authenticating.

As a SafeLinx Administrator I want to exclude certain URL paths from authentication requirements.
