Density Test includes deletion and volumes

Moved the calls to deletePodSync to BEFORE logDensityTimeSeries.  This is because the parser considers a line printed in logDensityTimeSeries to be the "end" of the test.  This change includes deletion in the "test window", but makes no other changes.

I also added volumes to the test, so that we can make sure that mounting and unmounting volumes are also taken into account for performance profiling.
