    """The etcd plugin collects information from the etcd key-value store. It
    is primarily used by Kubernetes/OpenShift clusters and is often run inside
    a container within the cluster.

    Collections will default to executing within an `etcdctl` container, if one
    is present, and only execute on the host if such a container is not
    currently running. The `etcdctl` name preference is adopted from OpenShift
    Container Platform deployments.

    This plugin is written for etcd v3 and later.
