The Cluster tab ([ADR 12](https://github.com/zoten/phoenix_dev_toolbar/blob/main/adr/12-cluster-and-eval-plugins.md)): this node and its connected nodes, with each one's
round trip time, process count, memory, OTP release and uptime. Not in
`:defaults`: add it to the toolbar's `plugins:`.

    config :phoenix_dev_toolbar, plugins: [:defaults, PhoenixDevToolbar.Plugins.Cluster]

Option: `refresh_ms:` how often the nodes are read while the tab is shown,
5000 by default (1000 to 60000).
