Agniva De SarkerandGitHub aac77cbd38 MM-57193: Standardize the cache names (#26441)
We use the same name for hit/miss/invalidation metrics.

The downside is that now we have conflated a full cache purge
and a single cache key invalidation into a single label, but
the advantage is that it's easier to monitor the usage of a single
cache.

And moreover, duplicating the same string across multiple places
increases the chances of making a mistake. Centralizing the cache
name only at instantiation simplifies the code.

After this, we would be ready to use Redis.
