If `forwarded` as configured as a tag (e.g. `var.tags: [forwarded]`) for the Zeek module then Filebeat will not add `host` fields to events. This is for use cases where Zeek is analyzing forwarded data (like from a network tap or mirror port). Relates: elastic#13920 (cherry picked from commit 018b17c)

Cherry-pick of PR #19113 to 7.x branch. Original message:
What does this PR do?
If
forwardedas configured as a tag (e.g.var.tags: [forwarded]) for the Zeek module then Filebeat will not addhostfields to events. This is for use cases where Zeek is analyzing forwarded data (like from a network tap or mirror port).Why is it important?
We want Filebeat to follow Elastic Common Schema. And setting host with the correct value is part of that. By setting (or not setting host) we can better interpret events. Without this change the Filebeat host is being attributed as the source even if data was received over a network tap or mirror port.
