estat: would like to have size summary stats

[sebroy]

When outputing size histograms with -z, it would be good to also have size data in the summary stats at the end. Right now, even with -z, the summary stats only show latency stats.

I'm not sure what you are asking for. Here is an example from the zpl collection. Throughput is based on size. Do you want average size columns for "zfs_read async", "zfs_write async", and "total"?

   bytes                                                 zfs_write async
