This utility is used to split the SecurityOptions field from the "/info" response into a slice of security.Option. It's effectively only used by the CLI to present the `docker info` output, but has a use in buildx to parse the response. We can assume the daemon returns a valid response, remove the error- conditions and fallback for legacy daemon versions (< 1.13), and limit it to parsing the response only.
