> Add new telemetry mode support for l3fwd-power.
> This is a standalone mode, in this mode l3fwd-power
> does simple l3fwding along with calculating
> empty polls, full polls, and busy percentage for
> each forwarding core. The aggregation of these
> values of all cores is reported as application
> level telemetry to metric library for every 500ms from the
> master core.
> The busy percentage is calculated by recording the poll_count
> and when the count reaches a defined value the total
> cycles it took is measured and compared with minimum and maximum
> reference cycles and busy rate is set according to either 0% or
> 50% or 100%.
