If running in a container return None. This is because DMI data is assumed to be not useful in a container as it does not represent the container but rather the host. This will do the following (returning the first that produces a result): 1) Use a mapping to translate `key` from dmidecode naming to sysfs naming and look in /sys/class/dmi/... for a value. 2) Use `key` as a sysfs key directly and look in /sys/class/dmi/... 3) Fall-back to passing `key` to `dmidecode --string`.
