Investigate node function on PKS crash loop

[scothis]

The node function is consistently entering a crash loop when running on PKS. It works on every other k8s runtime that we test.

See https://dev.azure.com/projectriff/projectriff/_build/results?buildId=2750&view=logs&jobId=88362a0d-4bdb-5566-6120-ca9d0da39f74&taskId=99c6fbac-d6aa-5ac3-890e-a553abc603e4&lineStart=61&lineEnd=62&colStart=1&colEnd=1

logs before the container crashes:

@fbiville there's probably something funny about ipv4 vs ipv6 with the node invoker (grpc) and pks.

This is the error I saw when running on PKS/vSphere:

please revert projectriff/fats@070a356 when this issue is fixed

I think we're stuck until grpc/grpc-node#1209 is solved.
