[dpdk-stable] [PATCH v3] usertools: fix input handling in telemetry script

[Andrius Sirvys <andrius.sirvys@intel.com>]

This commit removes the unnecesarry ast.literal_eval() function call
from the input handling, which now relies just on raw_input() to get
its input.

Fixes: 53f293c9a783 ("usertools: replace unsafe input function")

v2: Removed unnecessary comments
v3: Reduced scope of changes only to required Python 2 fix

Please note that the dpdk-telemetry-client.py script has a number of
issues with Python3 support. Fixing Python3 support is being deferred
to DPDK 19.11 release.
