TagList struct provides a way to avoid allocating memory when capturing metrics with upto 8 tags. This really helps achieve optimized paths for metric collection. While 8 tags works for close to 60-70% cases we still have quite a few cases where we the metrics are running above 8 tags.

The ask is to increase the number of tags for allocation free path from 8 to 12. We are running pretty close to 10 for some of our common metrics and we think that 12 should be a good tradeoff where it provides us a little wiggle-room while keeping the number still manageable and help most of the metric collections be allocation free.
