Tests

This test needs to be skipped for cloud.

Error

The error we get when running on cloud:

           │       + expected - actual
           │

Reason

Cloud runs in docker containers and we have logic that forks based on a specific config setting (xpack.monitoring.ui.container.elasticsearch.enabled). The test response is hard-coded to assume this isn't set so the tests will never pass running against a Kibana server with this config set.
