We want a new API version, since we made changes to the Node API that are not backward compatible (see PR in parent ticket).

Changes are mostly on node inventory fields in the "/api/20/nodes/<node_id> endpoint, and consist in changes on data format :

• in "storage", for each object in the list, "size" is in Bytes instead of MiB (e.g. previous value of `1` maps to a current value of `1 048 576`, still an integer)
• in "memories", for each object in the list, "capacity" is in Bytes instead of MiB
• in "fileSystems", for each object in the list, "totalSpace" and "freeSpace" are both in Bytes instead of MiB
• in "videos", for each object in the list, "memory" is in Bytes instead of MiB
• in "bios", for each object in the list, "releaseDate" has the ISO8601 date format YYYY-MM-dd'T'HH:mm:ssZZ instead of the previous display date YYYY-MM-dd HH:mm:ssZ
• "ram" field is in Bytes instead of MiB
