all: refactoring with latest update on dns package

All the server core functionalities (caches and forwarding) now
implemented inside "dns.Server".  The main function of this package are
for reading options from configuration file (or from command line options)
and watching changes from system resolv.conf.

There are also some major changes on configuration file.

*  "server.parent"  option now use URI format instead of IP:PORT.
   This will allow parent name servers to be UDP, TCP, and/or DoH
   simultaneusly.

*  "server.doh.parent" and "server.parent.connection" are removed,
   redundant with new "server.parent" format.

*  "cache.threshold" is renamed to "cache.prune_threshold".
