Can the Kibana dashboard decode the flowType to a string?

Describe the problem/challenge you have
I was playing around with the latest flow visualization code. I realized that the Kibana dashboards we provide do not decode the flowType and display it as an integer:

Describe the solution you'd like
Is it possible to transform it to a string: "PodToExternal", etc. IIRC the protocol identifier is also encoded as an integer (e.g. 6) but displayed as a string in Kibana (e.g. TCP).
We may also want to document the different values for this field in https://github.com/vmware-tanzu/antrea/blob/main/docs/network-flow-visibility.md#ies-from-antrea-ie-registry. Even though this is provided by go-ipfix, I think users would expect to find that information in this document.

I think this is possible. Tagging @zyiou as she is more familiar with elk-flow-collector config code.

Yes we can do that. Do we also need a new filter for flow type?

Yes, that would be good. However, in the current dashboard with Pod-To-Pod and Pod-To-Service flows, only IntraNode and InterNode are applicable. We need to think of ways to display Pod-To-External flows.
