EventScope EventType) PER_INSTANCEZcc_install_hotplugzInstall Hotplugas This module will install the udev rules to enable hotplug if
supported by the datasource and enabled in the userdata. The udev
rules will be installed as
``/etc/udev/rules.d/10-cloud-init-hook-hotplug.rules``.
When hotplug is enabled, newly added network devices will be added
to the system by cloud-init. After udev detects the event,
cloud-init will referesh the instance metadata from the datasource,
detect the device in the updated metadata, then apply the updated
network configuration.
Currently supported datasources: Openstack, EC2
