eve: Add information about Suricata version
Having that information on the eve log could be useful when trying to offer support,
since that file is the one folks often share, when some behavior is not as expected.
We could then skip asking that, if that info was already available.
Victor suggests that a way of achieving that would be to enable suricata.log by default and add that info to eve.json
It has also been discussed the possibility of adding a first record to the logs that would contain some of this type of info in a special record type
