💡Proxy http requests adding the cloudlfare access token

[0xalex88]

Describe the feature you'd like
To use CLI applications that cannot add a custom header to the requests, it would be nice to provide a proxy like cloudflard access tcp that adds the authentication token to each proxied request.
The usage would be something like:

cloudflared access http --hostname cloudflare-access.site.com --url localhost:8080

and have other CLI or any application in general just use http://localhost:8080 as the endpoint.

Describe alternatives you've considered
Right now the only way to have something like that working is to set the tunnel protocol to TCP and use cloudflared access tcp, that works but visiting the original protected endpoint doesn't work from the browser anymore
