Add header medatata flag
Add a new logstash configuration parameter to avoid adding header metadata and event.original to events
Closes https://github.com/logstash-plugins/logstash-input-http/issues/157
does this require docs changes?
@tommyers-elastic Yes, we'd need to document the new parameter, if we go this route. However, based on Joao's comment here https://github.com/elastic/obs-infraobs-team/issues/810#issuecomment-1266687847, this PR might not be needed anymore.
i think we still need to add the code into this repo, and then enable it in the wrapped (new) plugin.
Closing as not needed anymore (see https://github.com/elastic/obs-infraobs-team/issues/842 )
