unbound: add root zone file cache option

Add the possibility to use Unbound auto-zone: clause to
fetch complete root, arpa, in-addr.arpa, and ip6.arpa
zone files. This can speed up recursion when users
access many ccTLD or connection logging hits many PTR.

servers using http or AXFR (gTLD are unfortunately not as public).

Unbound can limit its protocol used for recursive queries.
