Patrick Crews 5b05d360b0 Bug#26887 - main.count_distinct3 fails randomly
Streamlined how we increase the size of our test table.
The new method shows run time decreased by ~60%.
This is not a guarantee that we will not see test timeouts (the random failures noted in the bug),
but it should significantly reduce the chances of this occurring.
