proxy stats output string.

Use Pion's Setting Engine to reduce Multicast DNS noise
...
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40123
The purpose of the patch is to prevent Pion from opening the mDNS port,
thus preventing snowflake from directly leaking .local candidates.
What this doesn't prevent is the resolution of .local candidates
once they are passed on to the system DNS.
