e577ab105e stats: add counter for timed out queries 
Add counter `num_queries_timed_out` meaning queries that were sitting in the
socket queue and waiting to being processed too long. There is no reason
to process such queries, so let's drop it in the very beginning of the
pipeline.

2e6ddd6032 netevent: parse and store rcv timestamp from sock

648ad4db6f Linting change. 
Remove config parser/lexer code as it's rebuilded every time but can
break adding new config options.
Also clean up the code base to avoid mixing actual code changes and lint
issues.

Added 2 new options to configure previously hardcoded

TCP connections to authority servers.
