Fix bundled urllib3 CVE-2026-44431 in resource-agents

Browse Source 
Backport upstream urllib3 fix for CVE-2026-44431
(GHSA-qccp-gfcp-xxvc) to the bundled urllib3 1.26.18 in
resource-agents. The patch adds header stripping in
connectionpool.py for cross-origin redirects when using
proxy pools directly, complementing the existing protection
in poolmanager.py. Both bundled locations (aliyun and gcp)
are patched.

Upstream patches:
 - 5ec0de499b.patch
Resolves: RHEL-178598
