This helper converts the input value of memory to Bytes.

Input needs to be a valid value as supported by k8s memory resource field.

This function aims to handle SI, IEC prefixes or no prefixes (cf. https://github.com/kubeflow/crd-validation/blob/master/vendor/k8s.io/apimachinery/pkg/api/resource/quantity.go#L44).

SI prefixes use power of 10 (e.g. 1e18 = 1 x 10^18) (m | "" | k | M | G | T | P | E).
|

IEC prefixes use power of 2 (e.g. 0x1p60 = 2^60) (Ki | Mi | Gi | Ti | Pi | Ei).
