This PR will introduce a new field to v1alpha1 configs that allows users
to set `dummy: true` when specifying interfaces. If present, we will
create a dummy interface with the CIDR information given. This is useful
for users that don't want to use loopback for things like ECMP (or want
more than one dummy interface).
The created dummy interface looked like this with `ip a`:
```
3: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN qlen 1000
link/ether 66:4a:e3:5f:38:10 brd ff:ff:ff:ff:ff:ff
inet 10.254.0.5/32 brd 10.254.0.5 scope global dummy0
valid_lft forever preferred_lft forever
```
Will close#2186.

fix: Fix when addressing set with kernel options
Signed-off-by: Niklas Wik <niklas.wik@nokia.com>
This includes a healthy refactor of the networkd code as well.
- Move netlink functionality to nic package
- Networkd facilitates the orchestration of the underlying interface configuration
- Networkd now stores the state of each interface configuration. This
should allow us to expose this information via api in the future.

This moves from translating a config into an internal config
representation, to using an interface. The idea is that an interface
gives us stronger compile time checks, and will prevent us from having to copy
from on struct to another. As long as a concrete type implements the
Configurator interface, it can be used to provide instructions to Talos.

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

This is a major rewrite of our network subsystem.
- This changes networkd to run as a standalone app versus internal goroutine
- This changes out the netlink package with the more idiomatic netlink/rtnetlink
packages
- This changes the initial network bootstrap/discovery from using a single
interface to attempting to bring up all interfaces
- This moves us back on to the upstream dhcp library
