Run unbound-control-setup, in order to create the certificates

for unbound-control. Seems to be required with unbound > 1.5

I updated one of my DNS servers today, and found unbound not starting up anymore automatically.
reason seems to be, that unbound-control now defaults to SSL secure communication.
However, its fairly hardcoded.

Do you think, unbound::remote should inherit unbound::params, and take the
group name, and $configdir from there?


all of those locations andd groups should be variables.
