frankly why in the world can't you just say "take certificates from this
and that folder"?
we have at least 4 backend servers which will soon start to generate
their certificates and sync them via rsync to
/var/lib/letsencrypt/hostname/ on the ATS machine and it makes no sense
at all that you need to generate a "ssl_multicert.config" listing for
every possible domain the RSA and ECDSA certificate by name
ssl_cert_name=/var/lib/letsencrypt/host1/*.pem
ssl_cert_name=/var/lib/letsencrypt/host2/*.pem
ssl_cert_name=/var/lib/letsencrypt/host3/*.pem
ssl_cert_name=/var/lib/letsencrypt/host4/*.pem
