TS-4436: Move hosts file implementation to `do_dns`
This moves the hosts file overrides down to the DNS layer instead of the
HostDBInfo layer. This means that each port will get its own entry in hostdb,
which will exist as its own HostDBInfo just like all the rest of the entries.
This also means we only have to do the check in the map on DNS lookup instead
of on each probe()
In addition to fixing the down status issues, this also means we no longer
need to keep old copies of the strings etc. since they are copied once
lookup_done is called.
Note: This patch is currently setting the TTL of the hosts file entry in
HostDBInfo as `HOST_DB_TIMEOUT_INTERVAL` Ideally this would be the time
remaining until the next hosts file sync, but I'm not sure if thats necessary--
thoughts?
