Idea here is that based on #5536, #3271, #5646 you can set a flag in the flow that is then added to eve.flow logs.

Q: Why can't we just set a flowbit based on flow bytes count and flow age?

I'm thinking:
1. have a setting in suricata.yaml that indicates the number of bytes and age of the flow after which a flow should be considered elephant flow.
2. allow overriding that setting for specific flows with a rule flag to the flow.bytes.. keyword that marks a flow elephant flow. Syntax could be something like flow.bytes_toserver:>=100000000,elephant incorrect since this does not take the age of the flow into account.
3. log elephant flow counter (unique elephant flows) in eve

Thoughts?

Note: What gets done with such a flow is not in scope of this ticket.

Initial idea of marking (NOT via rules) done here: https://github.com/OISF/suricata/pull/11645
Still thinking what the rules would look like.
