[ENHANCEMENTS] Possibility to Use Custom Preferred Certificate Authority

[prueckls]

I am using a custom PKI with self-signed certificates, so it would be beneficial to add the option to use a custom ACME provider for certificate generation and renewal. Currently, only the ACME Tool allows the use of custom ACME servers, which suggests that the programmatic logic is already in place.

Hi @prueckls

I think you will need to ping the one-time contributor who added this feature and ask if that is possible. My homelab is currently under maintenance & upgrade and I cannot test ACME related features at least for a few more months.

You can check out the PR and see if you can ping the contributor and ask for his help to extend his feature a bit more.
