* Node-health to a separate crate. * Initialize node_health outside of dapps. * Expose health over RPC. * Bring back 412 and fix JS. * Add health to workspace and tests. * Fix compilation without default features. * Fix borked merge. * Revert to generics to avoid virtual calls. * Fix node-health tests. * Add missing trailing comma.
