On non systemd systems (ie WSL) the progress view is always empty. Thus
this view is removed and the summary (formerly overview) view becomes
the last page of the setup with the reboot button. This button is
displayed dynamically when setup is complete.

This controller and view inherits from the subiquity identity, but
remove the "hostname" field. We are using composition over inheritance
for identityController as the UI builder is basing on the order of
declared elements as class variable and we can’t override that in the
metaclass when inheriting.
