      Umbrella ticket to cleanup any naming/metrics inclusion/exclusion requests that come up as we review tcmalloc's integration.

      • maxPerCPUCacheSize => maxPerCPUCacheSizeBytes
      • Rename fragmentation metrics
        • realized_fragmentation => peak_memory_used_to_memory_held_ratio
        • external_fragmentation => total_bytes_held
        • sampled_internal_fragmentation => estimated_size_class_memory_overhead
      • Add in per-CPU metrics behind diagnosticDataCollectionVerboseTCMalloc flag
