As a way to identify the K8s cluster from which the IPFIX record was exported.

The IE is of type string to allow for enough flexibility. This could be a qualified name or a UUID (for example). It should uniquely identify the cluster (to an external IPFIX collector).

@heanlan I was hesitating to name this "clusterUUID" and use the octetArray type. This would reduce the size of the value from 36 bytes down to 16 bytes. However, it doesn't seem like we really support octetArray in the library. Using the string type but not the typical string representation of a UUID also seems suboptimal.
I thought that a string "clusterId" field would be a bit more flexible, but I am not sure what is best. Let me know what you think.
For reference, this is the corresponding draft PR for Antrea: antrea-io/antrea#6769

It makes sense to me. I agree that a string type is more flexible, comparing to strict uuid type.
