The "dump_trace" CLI command is added to trigger
saving the trace dumps to the trace directory.
The tracing data are saved according to the EAL configuration
(explicit --trace-dir EAL command line parameter alters
the target folder to save). The result dump folder gets the name
like rte-YYYY-MM-DD-xx-HH-MM-SS format.
This command is useful to get the trace date without exiting
testpmd application and to get the multiple dumps to observe
the situation in dynamics.
