Suricata

Not sure how it should be reachable

with something like `suricata --list-keywords` or `suricata -T`, or another option

But it should output the info like json

"snmp.trap_type" : {
"enum_values": {
"colstart": 0,
"warmstart": 1,
"linkdown": 2,
}
}

Then we can check in CI that ./src/suricata --list-keywords=csv | grep enum are true because they have this field

It could be then also used by other tools like suricata language server I guess
