Help command giving wrong executable name

[Denil Chungath]

$ ettrace --help 
USAGE: perf-analysis-runner [--dsyms <dsyms>] [--launch] [--simulator] [--verbose]

OPTIONS:
  -d, --dsyms <dsyms>     Directory with dSYMs
  -l, --launch            Relaunch app with profiling from startup.
  -s, --simulator         Use simulator
  -v, --verbose           Verbose logging
  -h, --help              Show help information.

This is a known issue with argument parser as noted here. Basically it takes the name assigned to the command struct. We could override the _command property and that seems to work but that has been explicitly marked for internal use. The only other solution seems to be to rename the struct PerfAnalysisRunner to ETTrace.
