Subject: Make LRU caches ipv6 aware (#1810)

Simplest solution, keeping the existing cache data structure

TLS certificate cache is used for DTLS traffic, too.

Note that Ookla cache already works with ipv6 flows.

TODO:
 * make the key/hashing more robust (extending the key size?)
 * update bittorrent cache too. That task is quite difficult because
   ntopng uses a public function (`ndpi_guess_undetected_protocol()`)
   intrinsically ipv4 only...
