Description

Aurora already provides several metrics, which can be used to measure effectiveness of cache in upgrade process:

update_affinity_cache_expiration_removals
update_affinity_cache_explicit_removals
update_affinity_cache_removals
update_affinity_cache_size

(I believe they are added in https://reviews.apache.org/r/59231)

It will be great if we can provide these metrics up to each job level, so we can know whether a particular job has a good hit rate.
