Updating a single plugin can leave the installation with multiple
versions of @clusterio/lib. Passing the core package and every npm
installed plugin to a single npm update call lets npm resolve them
together.
UpdateAllRequest targets the controller or a host, requires both the
core update permission and core.plugin.update, and is gated by both
allow_remote_updates and allow_plugin_updates. The web UI Updates modal
gets an Update All action and ctl gets --all on the update commands.
