Improve Resource Cleanup Resilience

[michaelquigley]

Improve the resilience of the deallocateResources function such that it logs errors for each step, and continues proceeding through the cleanup process.

func (h *unshareHandler) deallocateResources(senv *store.Environment, shrToken, shrZId string, edge *rest_management_api_client.ZitiEdgeManagement) error {
    if err := zrokEdgeSdk.DeleteServiceEdgeRouterPolicy(senv.ZId, shrToken, edge); err != nil {
        return err
    }
    if err := zrokEdgeSdk.DeleteServicePoliciesDial(senv.ZId, shrToken, edge); err != nil {
        return err
    }
    if err := zrokEdgeSdk.DeleteServicePoliciesBind(senv.ZId, shrToken, edge); err != nil {
        return err
    }
    if err := zrokEdgeSdk.DeleteConfig(senv.ZId, shrToken, edge); err != nil {
        return err
    }
    if err := zrokEdgeSdk.DeleteService(senv.ZId, shrZId, edge); err != nil {
        return err
    }
    return nil
}
