[FR] Support ACME Renewal Information (ARI)

[ArchangeGabriel]

Two years ago, Let’s Encrypt announced ARI as way to check whether a certificate should be renewed: https://letsencrypt.org/2023/03/23/improving-resliiency-and-reliability-with-ari/

This is better than trying to renew daily and part of the use case for which this was intended.

Though, I’m not sure if this is in scope for this project. This should be part of the renewal script (see e.g. https://letsencrypt.org/2024/04/25/guide-to-integrating-ari-into-existing-acme-clients/), which is not covered here, but checking ARI is a bit more involved than writing one or two lines of shell script. So maybe acme-tiny could provide a way to check ARI?

For all of the info parsing "ARI" I can do "manually" (as in an script I run anyhow where Acme-tiny is part of), but one thing I think I can not do is the "replaces" part in the order... https://letsencrypt.org/2024/04/25/guide-to-integrating-ari-into-existing-acme-clients/

So... for me, as per spirit of Acme-tiny, it would be perfectly enough if I could have command line parameter passing the "replaces" argument with my own scripting for complete ARI support.
