ca.framework.cert.management.custom.san and "cloudstack-setup-databases -i" force a single string which must be a hostname

### problem

I need to add 127.0.0.1 to the certificate for $IP:9090/ and ca.framework.cert.management.custom.san is the way to do it, but the feature interprets the entry as a single string, such that the following value:
_cloudstack.internal, 127.0.0.1_

leads to this kind of alt name configuration:

_~# openssl s_client -connect 127.0.01:9090 /dev/null | openssl x509 -noout -text | grep DNS:
IP Address:192.168.0.123, DNS:**cloudstack.internal, 127.0.0.1**_

Note that "cloudstack.internal, 127.0.0.1" is a single string here, so the comma separation is not a thing as I assumed.

Replacing cloudstack.internal with 127.0.0.1 takes me one step further, in that 127.0.0.1 is added to the alt names, but is treated as a hostname, not an IP.

_~#openssl s_client -connect 127.0.01:9090 /dev/null | openssl x509 -noout -text | grep DNS:
IP Address:192.168.0.123, DNS:127.0.0.1_

To further aggravate me, even _cloudstack-setup-databases -i 127.0.0.1_ produces the same results, 127.0.0.1 is treated as hostname, not IP, just like the above.

報告された 4.21.0.0 KVM セットアップで、ca.framework.cert.management.custom.san と cloudstack-setup-databases -i 127.0.0.1 を使って、まず証明書の動作を再現します。示されているとおりに openssl s_client と openssl x509 で証明書を検査します。SAN 値が正しく解析され、IP アドレスがホスト名ではなく IP エントリとして表現され、複数の値が個別に処理されれば完了です。
