[dpdk-stable] [PATCH v2] usertools: fix telemetry python3 compatibility

[Laatz, Kevin]

> The client script for use with the telemetry library did not support
> Python3, as the data being sent over the socket was in string format.
> Python3 requires the data be explicitly converted to bytes before being
> sent. Similarily, the received bytes need to be decoded into string
> format.
> 
> Fixes: 53f293c9a783 ("usertools: replace unsafe input function")
> Fixes: fe35622659ed ("usertools: fix telemetry client with python 3")
> Fixes: d1b94da4a4e0 ("usertools: add client script for telemetry")
> Fixes: 4080e46c8078 ("telemetry: support global metrics")
