Unnecessry Virtual Node Updates #785
Description
Describe the bug
App Mesh Kubernetes controller issues unnecessary updates to virtual nodes in some cases when the virtual node has more than one backend. This will occur when the associated CRD is updated or when the controller performs a full reconciliation (every 10 hours by default). This does not impact the functioning or configuration of the mesh, but does result in unnecessary logs in CloudTrail.
Expected outcome
Backend ordering in the controller is not deterministic and is not important in App Mesh. The controller should not update the associated virtual node when only backend ordering has changed.
