AWS conditional policy support for aws:SourceIP and aws:SourceVPC

Issue

• Security policy requires that IAM User accounts with access keys be restricted to IP addresses and VPCs that are owned by the company so they are not used from unauthorized locations.
  The OpenShift Credentials Operator and the openshift-install command need to pass either the aws:SourceIP value if run outside of a VPC or aws:SourceVPC value if on a VPC to provide the same environment information of the execution environment so policies based on these values evaluate correctly.
