#97: Fix for Fatal failure on scaling down kubernetes cluster

Summary:
Fixed `ResolveInetAddresses` to use `VERIFY_RESULT` instead of `CHECK_RESULT`, so it
doesn't exit process with fatal failure in case of inet address resolution issues.

Test Plan: Jenkins. Create Kubernetes cluster, try to scale up and down.
