Short description

Christoph asked on the mailing-list whether this was supported, and it doesn't look like it is: https://mailman.powerdns.com/pipermail/dnsdist/2026-January/001648.html

At a quick glance it looks easy, add a new parameter to frontends (and backends?) and pass the supplied value to SSL_CTX_set1_curves_list, but I suspect the devil is in the details, as often.
