add template for creating cluster issuer and issuer about cert-manager

[hawksight]

Hey @Nello-Angelo, thanks for raising an issue here. Can I ask more of your use case to understand the request better?

Have you considered any other k8s native tools to auto generate resources such as Issuer or ClusterIssuer? This could be done with helm templates, or a policy tool such as Kyverno with generate policies.

Or is there a specific need to have this as a core feature to cert-manager

I won't have to describe an additional resource via Helm or terraform...
It would be comfortable to be able to create one such resource "out of the box"

If you think this is pointless, you can close the issue.
