> Allow fetching CPU cycles usage for all lcores with a single request.
> This endpoint is intended for repeated and frequent invocations by
> external monitoring systems and therefore returns condensed data.
> 
> It consists of a single dictionary with three keys: "lcore_ids",
> "total_cycles" and "busy_cycles" that are mapped to three arrays of
> integer values. Each array has the same number of values, one per
> lcore,
> in the same order.
> 
> Example:
> 
>  --> /eal/lcore/usage
>  {
>    "/eal/lcore/usage": {
>      "lcore_ids": [
>        4,
>        5
>      ],
>      "total_cycles": [
>        23846845590,
>        23900558914
>      ],
>      "busy_cycles": [
>        21043446682,
>        21448837316
>      ]
