> Currently, restarting all components (or all components that need config update) on a host (or multiple hosts) requires batching of multiple calls (one call per component type). This results in a whole bunch of requests being generated and floods the request history visible from the background operation popup.
> Restart should work in a similar way as "Start" and "Stop" for host components, where the FE can construct a single API call that results in a single request.
