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. https://mattermost.atlassian.net/browse/MM-57193 ```release-note NONE ```
