Web Token and OAuth authentication should be supported for requests by On Premise Pollers using internal URLs.

Currently, Web Token and OAuth tokens can only be requested from public refresh locations. This prevents REST API monitors running on On Premise Pollers from authenticating against services that are available only internally.

While REST API monitors can successfully access internal endpoints via On Premise Pollers, authentication fails because the token acquisition process requires externally accessible APIs.

Supporting token requests from On Premise Pollers would enable monitoring of internally hosted services secured with Web Token or OAuth authentication.
