* on `AsyncTable`, both `scan` and `scanAll` methods should result in `SCAN` table operations.
* the span of the `SCAN` table operation should have children representing all the RPC calls
involved in servicing the scan.
* when a user provides custom implementation of `AdvancedScanResultConsumer`, any spans emitted
from the callback methods should also be tied to the span that represents the `SCAN` table
operation. This is easily done because these callbacks are executed on the RPC thread.
* when a user provides a custom implementation of `ScanResultConsumer`, any spans emitted from the
callback methods should be also be tied to the span that represents the `SCAN` table
operation. This accomplished by carefully passing the span instance around after it is created.

This is no longer needed since we've transitioned to the shaded Jersey shipped in
hbase-thirdparty. Also drop supplemental models entry.

This is a demonstration of visualization of regions on the cluster. The visualization is a stacked
bar chart showing total storefile size per table per region server, with the x-axis being server
names, the y-axis being storfile size, and the bars stacked per table. The visualization is
generated entirely on the fly from within the browser, implemented using Vega Lite. So far, Vega
appears to handle rendering this visualization for a cluster of over 700 region servers with
approximately 300,000 regions.
Per [0], include an update to the top-level LICENSE.txt. Also update LICENSE files in all binary
distributions (i.e., jars), by way of LICENSE.vm. Vega uses a BSD 3-clause variant without
advertising clause, and as such is a "Category A" license, per [1].
No changes are made to the NOTICE files, as per the existing example of bundling the minified
JQuery, which is also a Category A license.

Trace table ExecService invocations as table operations. Ensure span relationships for both table
and master invocations.
