test: skip cluster cleanup in upgrade test
test: skip cluster cleanup in upgrade test

The cluster cleanup is tested in all of the test suites. Now that the
correct manifest test installer is being used for cleanup, the
upgrade tests are failing to delete the namespace due to some
finalizer that is holding on for some resource that wasn't cleaned
up properly. Let's just disable the cleanup for these tests since
it's tested in other test suites and not worth the time to
troubleshoot every resource getting cleaned up.
