Replacing Advice.class references with string construction.
This stops the JVM from loading the Advice classes which are used as templates for byte buddy and doesn't ever need to be run directly.
This eliminates ~130 class loads at start-up -- and saves 0.5MiB in metaspace
For mongo, use description if set, fallback to db name.
Memcache doesn’t have a good “instance name” that would work as service name, so clear it out for now.
