[CMD] Support dynamic trace (#7093)

Browse source 
Based on Hans Harder's patch.
Realize tracing cmd on console
output.
JIRA issue: CORE-6669
- Add FEATURE_DYNAMIC_TRACE
  feature.
- Add CmdTrace function.
- Re-define FIXME, ERR, WARN,
  and TRACE macros.
- Check CMDTRACE environment
  variable. If it was "ON", then enable
  dynamic trace.
