"""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.
