Description

The Impala debug memz webpage has a secret "detailed" mode you can access with a special URL, e.g.: http://localhost:25000/memz?detailed=true

The detailed output is vastly more useful than the non-detailed output, so we should make this the default.

We should also include some of the JVM memory metrics (maybe just totals) from the metrics page: http://localhost:25000/metrics
