The reason for doing this is:
Currently there are issues with AIX builders and azure resource that is causing our pipelines to break. The releng team is looking to fix these issues.
But we do not want this to be blocking for the next Infra Client 18 release.

This should be reverted immediately post the chef-client release: https://chefio.atlassian.net/browse/CHEF-1491
