Cherry-pick of PR #19494 to 7.x branch. Original message:

What does this PR do?

Fixes tls mappings in suricata module. Specifically:

  • add suricata.eve.tls.ja3s.string field
  • add suricata.eve.tls.ja3s.hash field
  • add suricata.eve.tls.ja3.string field
  • add suricata.eve.tls.ja3.hash field
  • set default_field to false for suricata fields
  • map suricata.eve.tls.ja3.hash to tls.client.ja3
  • map suricata.eve.tls.ja3s.hash to tls.server.ja3s
  • perform suricata.eve.tls.* -> tls.* mappings for all event types

Why is it important?

  • If the tls.* mappings aren't filled in the event doesn't show up in
    the TLS tab in the SIEM
  • default_field to false to stay under 1000 fields
