fix: remove unusued PerfInfoHandler code (#9328)

Browse Source 
- Removes PerfInfo admin API as its not OBDInfo
- Keep the drive path without the metaBucket in OBD
  global latency map.
- Remove all the unused code related to PerfInfo API
- Do not redefined global mib,gib constants use
  humanize.MiByte and humanize.GiByte instead always
