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

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

Connecting to /var/run/dpdk/rte/dpdk_telemetry.19707
--> /
{"/": ["/", "/ethdev/list", "/ethdev/stats"]}
--> /ethdev/list
{"/ethdev/list": [0, 1]}
--> /ethdev/stats,0
{"/ethdev/stats": {"rx_good_packets": 0, "tx_good_packets": 0,
 "tx_priority7_xon_to_xoff_packets": 0}}

This is a temporary script for testing purposes. Later versions
of the patchset will include a production ready version, which may
be merged into the existing dpdk_telemetry script.
