Add python 3.8 profiles; remove zoomark tests

The zoomark tests have served us well for many years.
At this point, they have been using a very antiquated
calling style for many years and are no longer where we catch
performance issues.
The performance suite now has a large number of individual
tests that catch issues very specifically and additionally
record just one performance count per test.   This also
allows us to remove the "replay" fixtures that were not
used for anything else.
