[Enhancement Request] Allow connectivity to multiple Elastic clusters and ability to toggle between them

[SamerHammer]

It would be great if we could allow connectivity to multiple Elastic clusters and the ability to toggle between them.
This would allow testing scenarios on different versions and/or different environments (e.g. DEV/UAT/Staging)

@SamerHammer , agreed. We'll see what we can do here.
