Problem

From elementary/os#745 (comment)

We're supplying the follolwing network configs that prefers NetworkManager instead of netplan for network management in the OS repository:

• https://github.com/elementary/os/blob/805f44d164c511034edd515c455fafeae280b6d2/etc/config/includes.chroot/etc/netplan/01-network-manager-all.yml
• https://github.com/elementary/os/blob/805f44d164c511034edd515c455fafeae280b6d2/etc/config/includes.chroot/etc/NetworkManager/conf.d/10-globally-managed-devices.conf

This works, but it won't be supplied as an system update and requires a build of ISO when we update these files.

Proposal

• Check the behavior for how the package installs for someone that's already manually created that file (see Prevent override 10-globally-managed-devices.conf overwritten by package update os#745 (comment))
• Import the above two files in default-settings → Import network configurations from the os repository #325
• Remove the above two files from os → Remove network configurations os#748
