[pve-devel] [PATCH manager 2/3] api: acme: dns-plugin: conditionally pass proxy to acme.sh wrapper

[Stoiko Ivanov <s.ivanov@proxmox.com>]

partially fixes #3536

If an acme (dns) plugin has set the 'use-proxy' flag, pass
the http_proxy configured in datacenter.cfg.

The setting is configurable for each dns-plugin, based on the
assumption that some dns-apis might be 'local' (e.g. a pdns-server in
the internal network) and communication with them must not pass
through the proxy.

The implementation follows the one in PMG
