an HServerInfo.  This looks like something that would belong in there rather than in HSL?

Hi Michael,

As Ted mentioned, HServerInfo is deprecated (per https://issues.apache.org/jira/browse/HBASE-1502)

> HBASE-3512 is about listing loaded cp classes at shell. To make it more generic, we need
a way to report this piece of information from region to master (or just at region server
level). So later on, we can display the loaded class names at shell as well as web console.
