This patch adds the option --list (-l) to dpdk-telemetry.py which will
print all of the available dpdk file-prefixes that have telemetry enabled.
The prefixes will also be printed if the user passes an incorrect prefix
in the --file-prefix (-f) option.
Depends-on: series-19390 ("improve telemetry support with in-memory mode")
