dnsproxy: Add cache refreshing logic

This patch adds logic to the DNS cache where it will refresh, rather than purge,
popular DNS entries when they expire. This will cut down latency for the user,
since he doesn't have to wait for a DNS resolve for his popular entries.

It also makes changing DNS servers (say, when joining a VPN) less expensive,
since the popular entries from the cache will be refreshed after the join,
rather than just being dropped
