Manually purge cached resources from Cloudflare from Drupal site uses Guzzle HTTP client instead of cURL

This module provides any Drupal user with permissions to manually purge
Cloudflare cache. Purge Cloudflare cache for any Drupal site/domain.

How is Cloudflare Purge secure?
It uses custom CSRF token in Drupal. It also uses Guzzle HTTP client request
for all API calls. So it's not vulnerable to CSRF exploits and avoids security
risk.
