While working on HBASE-8877 I noticed that HRegion.heapSize was missing
many things. I fixed FIXED_OVERHEAD as part of the issue, but didn't try
to fix about a dozen missing fields from DEEP_OVERHEAD (though added
comments) or the actual dynamic heapSize().
Are we still trying to keep these up to date? Should I file a JIRA?
