Tests for v0.3 release are failing

New functionality for cluster support was added in #94; however the tests for the release candidate are timing out, see #92; therefore blocking the release.

@murphyjacob4 can you please take a look?

Hi, I've updated the networking infrastructure that is used to route the integration test in Cloud Build to the Memorystore instance used for testing.

I reran the most recent nightly and it seems to be succeeding now. Can we retry the test for the linked PR?

Thank you @murphyjacob4 . The tests are now passing.
