Use Network-Manager and Netplan as default renderers for RHEL and Fedora (#1465)
This is adapted from Neal Gompa's PR:
https://github.com/canonical/cloud-init/pull/1435
The only difference is that we are not modifying renderers.py (thus
modifying the priority of all distros), but just tweaking cloud.cfg to
apply this change to Fedora and RHEL. Other distros can optionally
add themselves afterwards.
net: Prefer Netplan and NetworkManager renderers by default
NetworkManager is used by default on a variety of Linux distributions,
and exists as a cross-distribution network management service.
Additionally, add information about the NetworkManager renderer to
the cloud-init documentation.
Because Netplan can be explicitly used to manage NetworkManager,
it needs to be preferred before NetworkManager.
This change is a follow-up to #1224, which added the native
NetworkManager renderer.
This patch has been deployed on Fedora's cloud-init package throughout
the development of Fedora Linux 36 to verify that it works.
This should also make it tremendously easier for Linux distributions
to use cloud-init because now a standard configuration is supported
by default.
