Replace Basic Zone creation in UI by 'Easy Mode' (Advanced Zone)

[Wido den Hollander <wi...@widodh.nl>]

Hi,

I've brought this up before and even opened a PR [0] to disable Basic
Zone creation, but after some discussion and good feedback I think we
can do it differently.

In the UI we now have a wizard popping up when starting for the first
time where you can then create a new zone.

I think we can remove the Basic Zone here as it is right now and add a
'Easy Mode' where a Advanced Zone is created with vlan://untagged as
isolation with Security Grouping enabled just as it would be with a
Basic Zone.

Now, I'm not a UI nor JavaScript expert at all, so I wouldn't know how
to fix this, but is there somebody who wants to jump in and help with this?
