Hi,

If you're using an external Elasticsearch instance, is there a way to disable the default instance bundled?

Couldn't find anything in the docs...

From https://github.com/apiman/apiman/blob/master/distro/es/src/main/java/io/apiman/distro/es/Bootstrapper.java#L49 it doesn't seem like it

Unless there is something I'm not aware of, would it be useful to have a config option to turn off the embedded ES instance? 

For instance a apiman.distro-es.enabled=false in https://github.com/apiman/apiman/blob/master/distro/es/src/main/java/io/apiman/distro/es/DistroESConfig.java or something.
