Scale Up Integration Test Fix

[Seth Saperstein]

overview

Scale up test is being commented out to get integration tests working on github actions. The issue is that github hosted runners only allow 8gb memory and 2 cpu by default. The scale up test requires 2 flink clusters to run simultaneously, one with 2 tm's with 2 task slots each and one with 1 tm with 2 task slots. Other tests only require 1 tm per flink cluster and have been squeezed into the github hosted runner by decreasing parallelism during testing.

To get this test to run, we'll need to use larger github runners which is currently in beta.
