Display notification when wrong password error is detected

A new notification will be generated and displayed when the wrong
password error is detected for the current connection.
It will be dismissed when:
- the user manually dismiss it or tap on it
- attempting a new Wi-Fi network connection
- timeout, currently set to 5 minutes

The current landing page for the notification is the network list page,
it will be updated when the new landing page is ready (dialog prompting
for the new password).
