Added a property to userdata to allow a network interface to be ignored, such that Talos will perform no operations on it (including DHCP). Also added kernel commandline parameter (talos.network.interface.ignore) to specify a network interface should be ignored. Also allows chaining of kernel cmdline parameter Contains() where the parameter in question does not exist. Fixes #1124 Signed-off-by: Seán C McCord <ulexus@gmail.com>
