The power library contains some variables which are currently set by
defines, hard-coded values or set using sysfs values. In order to
configure these, code changes and recompiles are required, making
configuring these variables tedious.
This patchset introduces some new get/set APIs which allow users and
applications to configure there settings to suit their use-cases.
In addition, CLI options have been added to l3fwd_power to demonstrate
how an application could use these APIs to expose the options to users
without needing code changes to configure them.

Hi Kevin,
We also have documentation for this library under
`doc/guides/prog_guide/power_man.rst`, which documents methods exposed
by the PMD power management. That document needs to be updated with the
new additions :)
