elastic
Elastic client now uses url_prefix from host dictionary.
I have several Elastic clusters hosted in a single Kubernetes cluster. For policy reasons, I can only expose port 443. Instead, I use different URL paths to get the right combination of cluster and elastic/kibana. As a result, Rally was failing as --target-hosts would end up stripping most of the URL.
This change checks if a URL prefix has been configured and passes that through in the ES client factory.
I have ran make check-all, the unit tests all work but there are some integration test failures. However, I also get the same failures on master so I'm unsure what to do with them.
I have signed the contributor agreement.
Thanks for the contribution - Yes, the integration tests require some API keys etc, so tend to be run via the CI. I unblocked the CI for your changes, so lets let them run there and see.
