Support certificate profile selection

[JensSpanier]

In preparation for the upcoming support of IP address certificates at Letsencrypt, I have added the option to select certificate profiles.

So if you want to issue an IP address certificate, this is the command for Letsencrypt (staging):
acme.sh --issue -d 203.0.113.195 -w /home/username/public_html --server letsencrypt_test --certificate-profile shortlived --days 6

Closes #6193

thank you, this looks interesting. I hope the maintainers will get around to a review.

Great work on this!
To make it even more robust, what if we first adjusted the logic to dynamically pull the ACME profile from the CA's directory before making the request? This aligns with their best practices for clients.
Then, as a fallback, we could also add the specific error handling for the invalidProfile ACME error. This would create a very resilient implementation.
Implementing this would also close #6193.
