Generating certificates with the cert sub-command now requires either: 1) a CA
to be provided with --ca or --ca-cert/--ca-key; or 2) make them self-signed
with the --self-signed option. Generating a CA on the fly is no longer
supported. The --keep-ca-key option is removed and the tool throws an error
saying the CA needs to be generated separately if the option is specified.
This is a follow-up PR for #61884, which deprecated the "ca-on-the-fly" usage.
Generating a CA on the fly is an attempt at workflow optimisation that was
inherited from certgen. There are potential pitfalls with this approach. Overall
it is recommended to separate the step of CA creation and mandate a CA to be
specified when generating certificate.
This PR add a deprecation message if the cert command is used without specifying
a CA. A follow up PR will throw error for this usage in 8.0.
For use case where we explicitly trust a certificate without needing a CA, e.g.
SAML message signing, the PR adds a --self-signed option to the cert sub-command
to generate self-signed certificate.
