services: certbot: Associate one certificate with several domains.
* doc/guix.texi (Certificate Services): Document <certificate-configuration>, the change from domains to certificates and the fact that their path is now derived from their name. * gnu/services/certbot.scm (<certificate-configuration>): Add and export it. (certbot-configuration, certbot-command, certbot-activation, certbot-nginx-server-configurations, certbot-service-type): Replace 'domains' with 'certificates'. (certbot-nginx-server-configurations): Use only one nginx-server-configuration and use all certificate domains as the server-name.
