This provides a way to get ahold of LWS_WITH_CONMON telemetry from Secure
Streams, it works the same with direct onward connections or via the proxy.
You can mark streamtypes with a "perf": true policy attribute... this
causes the onward connections on those streamtypes to collect information
about the connection performance, and the unsorted DNS results.
Streams with that policy attribute receive extra data in their rx callback,
with the LWSSS_FLAG_PERF_JSON flag set on it, containing JSON describing the
performance of the onward connection taken from CONMON data, in a JSON
representation. Streams without the "perf" attribute set never receive
this extra rx.
The received JSON is based on the CONMON struct info and looks like
{"peer":"46.105.127.147","dns_us":596,"sockconn_us":31382,"tls_us":28180,"txn_resp_us:23015,"dns":["2001:41d0:2:ee93::1","46.105.127.147"]}
A new minimal example minimal-secure-streams-perf is added that collects
this data on an HTTP GET from warmcat.com, and is built with a -client
version as well if LWS_WITH_SECURE_STREAMS_PROXY_API is set, that operates
via the ss proxy and produces the same result at the client.

lws minimal secure streams proxy
Operates as a secure streams proxy, by default on a listening unix domain socket "proxy.ss.lws" in the Linux abstract namespace.
Give -p to have it listen on a specific tcp port instead.
build
$ cmake . && make
usage
| Commandline option | Meaning |
|---|---|
| -d | Debug verbosity in decimal, eg, -d15 |
| -f | Force connecting to the wrong endpoint to check backoff retry flow |
| -p | If not given, proxy listens on a Unix Domain Socket, if given listen on specified tcp port |
| -i | Optionally specify the UDS path (no -p) or network interface to bind to (if -p also given) |
