Support for variables in acme_certificate identifiers #104
Description
Feature Overview
Currently, the acme_certificate directive in ngx_http_acme_module requires static identifiers or automatically inherits them from the server_name directive. This prevents the module from being used in truly dynamic, multi-tenant environments where domain names are determined at runtime (e.g., via the $host variable or other custom variables).
Allowing "acme_certificate issuer $host [key=alg[:size]];" would enable NGINX to automatically handle certificate issuance for any domain pointed at the server, provided it passes validation.
