[dpdk-dev] [RFC 3/6] usertools: add process-info python script

[Ciara Power <ciara.power@intel.com>]

From: Bruce Richardson <bruce.richardson@intel.com>

This patch adds a python script that can be used with the process_info
library. It connects as a client to the process_info socket, and allows
the user send a command and see the JSON response.

The example usage below shows the script connecting to the process_info
socket, and sending two basic commands entered by the user. The response
for each command is shown below the user input.

Connecting to /var/run/dpdk/rte/process_info.22103
--> /
{"/":["/","/eal:app_params","/eal:params","/eal:version"]}

--> /eal:version
{"/eal:version":"DPDK 20.02.0-rc0"}
