pdns-recursor for PowerDNS
After the introduction of PowerDNS in cPanel/WHM 60, currently it requires that we use an external DNS caching resolver due to the lack of functionality in PowerDNS itself.
PowerDNS has a separate recursor (https://www.powerdns.com/recursor.html) - which can be used to bring back a caching resolver when using PowerDNS.
The resolver itself works out of the box, it requires no configuration changes, by default it listens to localhost / 127.0.0.1 meaning that it can't be used as a open resolver from the beginning unless people actually do a config change.
It also makes me believe that adding this should be pretty straight forward - anyone can do it already, simply by doing yum install pdns-recursor.
But it would be ideal if it could be done automatically when choosing to use PowerDNS during the nameserver selection.
If this isn't very easy, then at least in the suggestion when selecting it, give a link to the recursor, so people are aware that it exists.
