The zuul user on zuul-dev.o.o could not connect to review-dev.o.o because the /home/zuul/.ssh/known_hosts file did not get created. This causes zuul-merger to fail because it needs that to clone repos from review-dev.o.o. This change passes the gerrit public key from review-dev.o.o so that puppet can create the known_hosts file.
