Downloading external resources degrades performance

[pemsith]

Description
Tasks that directly download resources from external sources during runtime (e.g., get_url) causes high memory usage. This issue is particularly noticeable in environments with large-scale deployments or limited system resources. There are couple of instances in different files that we are reporting as part of this bug that we would like to get resolved.

openshift-tools/openshift/installer/vendored/openshift-ansible-3.9.40/playbooks/azure/openshift-cluster/launch.yml
openshift-tools/openshift/installer/vendored/openshift-ansible-3.11.28-1/playbooks/azure/openshift-cluster/launch.yml
--- - name: download acs-engine
get_url:
url: "{{ item }}"
dest: "{{ tmp.path }}/"
with_list:
- "http://acs-engine-build-azure.svc.ci.openshift.org/acs-engine"
- "http://acs-engine-build-azure.svc.ci.openshift.org/openshift.json" ---

Expected behavior
The playbook should avoid fetching resources directly from external URLs to prevent high memory usage. Instead:

• Pre-fetch the required resources to a control machine or staging area ahead of deployment.
• Use local copies or mirrors for fetching files.
• This approach would reduce memory usage and improve the performance and reliability of deployments.
