`UtilityNetworkTrace` - Auto zoom to trace extent

[dfeinzimer]

Closes #947

Aligns the component with the following design spec:

By default, the control will zoom to the trace result area. This feature can be disabled by setting the AutoZoomToTraceResults property of the control to false.

Behavioral changes:

• When a trace completes, the viewpoint is automatically set to the extent of the trace's results.
  • This can still be disabled by the user under the "Advanced Options" when creating a trace.
• While browsing the list of completed traces, the viewpoint now changes to reflect the extent of the currently selected trace.

Does the design state that the extent should be buffered a bit to fully show the result (so it doesn't stretch right to the edge of the display)?

I'm not seeing any language about it in the spec but we do add a buffer here. Should we expand it a bit more?

Should we expand it a bit more?

No, that's fine. I missed that a buffer was already being applied. Thanks.
