There are many stats for which default tag extraction rules should be written. The following list was generated from #21397.

For each match below, rules should be added to source/common/config/well_known_names.cc, and the TODO should be deleted.

The list was generated with grep -R -A 3 "TODO(ggreenway): add tag extraction rules." test/*.
