Add a new endpoint for "resource" metrics `/v2/metrics/resource` This should return system metrics related to drives, network, CPU and memory. Except for drives, other metrics should have corresponding "avg" and "max" values also. Reuse the real-time feature to capture the required data, introducing CPU and memory metrics in it. Collect the data every minute and keep updating the average and max values accordingly, returning the latest values when the API is called.
