Commit Message

Power, Ciara Jan. 21, 2020, 5:03 p.m. UTC
  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")

V2: added future import for unicode literals to ensure consistency of
data types for Python2 and Python3.
