// GetContainerOOMScoreAdjust returns the amount by which the OOM score of all processes in the
// container should be adjusted.
// The OOM score of a process is the percentage of memory it consumes
// multiplied by 10 (barring exceptional cases) + a configurable quantity which is between -1000
// and 1000. Containers with higher OOM scores are killed if the system runs out of memory.
// See https://lwn.net/Articles/391222/ for more information.
// OOMScoreAdjust should be calculated based on the allocated resources, so the pod argument should
// contain the allocated resources in the spec.

// isSidecarContainer returns a boolean indicating whether a container is a sidecar or not.

// this function uses available indicators (container.RestartPolicy == v1.ContainerRestartPolicyAlways)
// to make that determination.
