retrieve_certificate stack dns_key ~hostname ~key_type ~key_data ~key_seed ~bits server_ip port generates a private key (using key_type, key_data, key_seed, and bits), a certificate signing request for the given hostname and additional_hostnames, and sends server_ip an nsupdate (DNS-TSIG with dns_key) with the csr as TLSA record, awaiting for a matching certificate as TLSA record. Requires a service that interacts with let's encrypt to transform the CSR into a signed certificate. If something fails, an exception (via Lwt.fail) is raised. This is meant for unikernels that require a valid TLS certificate before they can start their service (i.e. most web servers, mail servers).
