ubiquity must allow debconf database access when ubuntu-drivers executes apt-get install

using pass through and what not.

Currently prepare stage of ubiquity executes ubuntu-drivers install.

When doing so, it installs packages in the live system.

During that time debconf database is locked and inaccesisble, and nvidia packages fail to install correctly. And possibly other dkms pacakges.

There are facilities to create overlay debconf database and use passthrough protocol to ensure that installing packages and talking to debconf works during that time.

Also one has to re-enable preconfigure of packages, such that config scripts are run, cause ubiquity disables those at the momement.

I am considering creating ephemeral database in /run and set DEBCONF_DB_OVERRIDE, such that even when config.dat is locked, one can start ubiquity.

Separately, I want to wipe that ephemeral database on quiting the installer, to wipe the state machine it has generated.

At the moment, if one answers a couple of questions, closes and restarts the installer, the shadow state / previous answers are shown and used.
