Application Service URIs not treated as URIs

[martindale]

Using URIs in Application Service configuration do not appear to be parsed as URIs, but rather with some kind of custom heuristic.

Steps to reproduce

• Configure an Application Service using an URI like https://USERNAME:PASSWORD@somehost.local/services/matrix
• Observe failed connection to :PASSWORD@somehost.local

If this were parsed as a URI, which I believe is the intention, the HTTP client should receive correct Authorization headers for the application service.

IMO this should not be fixed as it's incompatible with matrix-org/matrix-spec-proposals#2832

I think that supporting using USERNAME:PASSWORD in application services would conflict with the use of an access_token? So even if we did correctly parse the URL we'd likely just reject it. Do you have a use case for this?

sounds like this isn't a thing we have a viable usecase for.
