[Script request]: Prometheus Blackbox Exporter

Description

Prometheus Blackbox Exporter enables monitoring of external endpoints (HTTP, HTTPS, TCP, ICMP, DNS, etc.) from the outside, to verify availability, response times, and connection quality. To my knowledge, the current ProxmoxVE Helper-Scripts collection includes a prometheus-pve-exporter script that integrates internal metrics, but it does not support external endpoint probing.

By introducing a Blackbox Exporter integration, users could complement the internal metrics collection with external health checks—making full-stack monitoring more complete in Proxmox environments.

To my understanding, it should be relatively straightforward to implement using the existing scraparr
script as a jumping-off point, since it already demonstrates a similar lightweight exporter setup flow.

Due Diligence

• I have searched existing scripts and found no duplicates.
• I have searched existing discussions and found no duplicate requests.
