   @dimberman Requests were hanging due to idle connection time-out on Azure Firewall. Timeout is set to [4 minutes](https://docs.microsoft.com/en-us/azure/firewall/firewall-faq#what-is-the-tcp-idle-timeout-for-azure-firewall). Kubernetes lib under the hood is using urllib3 PoolManager which reuse connections. On timeout RST package is send which cause urllib3 to hang indefinitely. I'm going to provide fix for it.
