    - injects the CNI plugin config to the CNI config file
        - CNI installer will try to look for the config file under the mounted CNI net dir based on file name extensions (`.conf`, `.conflist`)
        - the file name can be explicitly set by `CNI_CONF_NAME` env var
        - the program inserts `CNI_NETWORK_CONFIG` into the `plugins` list in `/etc/cni/net.d/${CNI_CONF_NAME}`
