replace the certs with those generated by openssl

These are different certs to the ones extracted by puppetca, but they work with
rabbitmq.  There's probably something in the structure of the ones generated by
puppetca that we may be able to reduce/translate, but with those old certs you
get the 'erlang hates you' treatment.
