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")

Nit: I think it might be cleaner to move this down to just before the file prefixes print out, so it doesn't print out when no apps are available.
