Elasticsearch Integration - Support setting condition

[BenB196]

Request

Add the ability to set condition values on both the Logs and Metrics sections of the Elasticsearch module

Use Case

I was looking to switch from using Metricbeat to the Elasticsearch integration for monitoring some Elasticsearch clusters. However, I noticed that this integration mainly seems to be developed with standalone Elasticsearch instances in mind, and not clusters on things like Kubernetes deployed via ECK. The ability to set condition here I think would allow for being able to use this integration with Kubernetes deployed clusters.
