Display blocked "Deep CNAME" domains in Pi-hole tail & query

[yubiuser]

@DL6ER

1. Add logging to pihole -q
2. Add logging to pihole -t

My summary is:

1. Is not really possible as CNAME blocking depends on external information (the entire path of CNAMEs) and, hence, is only possible at real time as (a) the paths may change upstream and (b) it would be necessary to query all domains in the entire Internet to find out if they contain a CNAME element which is blocked. It is not possible to ask a DNS server something like "tell me all domains where CNAME x.y.z is somewhere in the path".
2. This we can do, I will have to research how to do it without hooking into the dnsmasq code even more, but it will surely doable somehow.

Closing this request as implemented with the release of FTL v5.2 (Pi-hole FTL v5.2 Released).
