A regular (non-regex) file: upstream needs to strip the prefix so that it is equivalent to "mounting" the specified directory under the configured path in the URL space, but with regex rewriting the target path is determined by the rewriteTarget.
Fixesoauth2-proxy/oauth2-proxy#2242
* Add support for unix socket as upstream
* Add CHANGELOG.md entry
* Add Unix socket documentation
* Don't export unixRoundTripper, switch from string prefix to Scheme match
* Add basic unix server mock
* Add some tests and comments
* Use the httputil.NewSingleHostReverseProxy instad of yhat/wsutil for websocket proxying. This correctly handles 404 responses with keep-alive by terminating the tunnel rather than keeping it alive
* Tidy up dependencies - yhat/wsutil is no longer required
* Update changelog to include reference to 1348
