caddyhttp: add http.request.local{,.host,.port} placeholder (#6182)
* caddyhttp: add `http.request.local{,.host,.port}` placeholder

This is the counterpart of `http.request.remote{,.host,.port}`.

`http.request.remote` operates on the remote client's address, while
`http.request.local` operates on the address the connection arrived on.

Take the following example:

- Caddy serving on `203.0.113.1:80`
- Client on `203.0.113.2`

`http.request.remote.host` would return `203.0.113.2` (client IP)

`http.request.local.host` would return `203.0.113.1` (server IP)
`http.request.local.port` would return `80` (server port)

I find this helpful for debugging setups with multiple servers and/or
multiple network paths (multiple IPs, AnyIP, Anycast).

* caddyhttp: add unit test for `http.request.local{,.host,.port}`

* caddyhttp: add integration test for `http.request.local.port`

* caddyhttp: fix `http.request.local.host` placeholder handling with unix sockets

The implementation matches the one of `http.request.remote.host` now and
returns the unix socket path (just like `http.request.local` already did)
instead of an empty string.
