Lowercase host_specific_hostname_identity to prevent troubles If uppercase is used, certain tools (like certbot) would cause trouble. They would retrieve a certificate for the lowercased domain name, but we'd try to use it from an uppercase-named directory, which will fail. Besides certbot, we may experience other trouble too. (it hasn't been investigated how far the breakage goes). To fix it all, we lowercase `host_specific_hostname_identity` by default, which takes care of the general use-case (people only setting that and relying on us to build the other domain names - `hostname_matrix` and `hostname_riot`). For others, who decide to override these other variables directly (and who may work around us and introduce uppercase there directly), we also have the sanity-check tool warn if uppercase is detected in any of the final domains. 6 years ago			`when: "matrix_coturn_turn_static_auth_secret == ''"`
