Currently networking screen shows networks settings based on interfaces.

This is a good visualization of the networking setup at a run time from a sys admin perspective, but it does not show the underlying connection configuration to the user.

We propose to add, not replace, the widget which will list existing connections, wired or wireless and allow configuration of them similar to what desktop network connection editors allow.

Configurations done in the Connection widget and in the Interfaces widgets need to be consistent.

Note: main stakeholder for this widget is the Anaconda team, thus we should test at least manually, that it works in the initramfs environment similar to described in COCKPIT-1371
