/**
 * Serialize a given cell to a List of Objects that jsonMapper knows how to turn into strings.  Format is
 *
 * human_readable_name, value, timestamp, [flag, [options]]
 *
 * Value is normally the human readable value as rendered by the validator, but for deleted cells we
 * give the local deletion time instead.
 *
 * Flag may be exactly one of {d,e,c} for deleted, expiring, or counter:
 *  - No options for deleted cells
 *  - If expiring, options will include the TTL and local deletion time.
 *  - If counter, options will include timestamp of last delete
 *
 * @param cell     cell presentation
 * @param cfMetaData Column Family metadata (to get validator)
 * @return cell as serialized list
