What this PR does:
#4344 improved prealloc behavior gettings us 10-40% working set reductions across all our clusters. It also introduced a metric to help track prealloc "misses". This PR by default will not change any Tempo behavior but will give better information and tunable parameters for precise tuning of the prealloc buckets.
