These PRs need to be reviewed:
(added backports to make it easier for you to review)
logstash-input-http_poller need backport to 3.x
logstash-output-rabbitmq need backport to 4.x
logstash-output-elasticsearch 7.x
Backported changes in logstash-input-http_poller to 3.x and logstash-output-elasticsearch to 7x .
The problem in logstash-output-rabbitmq is already fixed in 4.x, so I didn't have to backport.
@dedemorton all of theses changes are reviewed, merged and published.
