* Replace `container_linux_version` variable with `os_version`
* Add `network_ip_autodetection_method` variable for Calico host IPv4 address detection
* Use Calico's default "first-found" to support single NIC and bonded NIC nodes
* Allow [alternative](https://docs.projectcalico.org/v3.1/reference/node/configuration#ip-autodetection-methods) methods for multi NIC nodes, like `can-reach=IP` or `interface=REGEX`
* Deprecate `container_linux_oem` variable
