Networkinga The root of the Networking hierarchy in cloud-init.
This is part of an ongoing refactor in the cloud-init codebase, for more
details see "``cloudinit.net`` -> ``cloudinit.distros.networking``
Hierarchy" in CONTRIBUTING.rst for full details.

settle process as is required for the given DeviceName to be
present in the system. (This may include skipping the settle
process entirely, if the device already exists.)

Specifically, this will call `self.settle` 5 times, and check after
each one if the physical devices are now present in the system.

The NetworkConfig from which to extract physical devices to wait
for.
:param strict:
Raise a `RuntimeError` if any physical devices are not present
after waiting.
