networks: Fixes for networks wizards
- Make first wizard steps for router configuration and Internet connection type
private. Since they run after the admin user page, the steps can run for logged
in users.

- Add option to the Internet connection type wizard, to let the user say that
they don't know the type. This allows them to have a stress-free first setup
experience. The option can act as if they have don't have public IP address at
all. This is an extension of the proposed user experience.

- Implement class based views for simplicity.

- Update various IDs for consistency (even though other IDs in the networks
module don't conform).

- Iron out inconsistent terminology. Setup vs Configuration, Help vs. Wizard,
etc.

Tests performed:

- Run first boot wizard from the beginning. Notice that both the wizard steps
appear properly after the user login step (without permission denied problems).
When not logged in, accessing the wizard steps with URL should redirect to login
page.

- During first boot wizard, select 'Skip this step' in both the steps after
selecting non-default options. Values set should be default options as confirmed
from networks page.

- During first boot wizard, select non-default values, the values should be set
properly as confirmed from networks page.

- From the networks page select each value of the wizard. The option should get
saved properly.

- In case of Internet connection type, when the wizard values changes, the
networks page should reflect the value properly. This should also show properly
after skipping the step during first boot.

- During first boot, the default value for Internet connection type should be 'I
don't know' and router configuration should be 'Not configured'.
