During a consulting engagement with a customer, I found that their Elasticsearch clusters were configured in a very particular way that makes it very hard to create a trust-store for the JVM to be able to validate the server certificates for the ES members.

For this reason, I believe it would be useful to modify our code for the Events Forwarder, the Alarms History Forwarder, and the Situations Feedback to be able to ignore certificate validations.

There are already other OpenNMS features with this feature in place (for similar reasons).
