Oliver Walsh ceaf79d191 Ensure nouveau is blacklisted in initramfs too 
To ensure dracut does not load nouveau we need to explicitly disable it via
omit_drivers.
This change adds a method to drop in arbitary dracut conf files to an element
which are picked up by dracut-regenerate and included in the chroot where we
run dracut.

The disable-nouveau element just adds a conf file with
`omit_drivers += " nouveau"`
The default dracut conf files in /usr/lib include a similar file to omit the
nvidia kernel modules.

dracut-regenerate

Adds the possibility of regenerating dracut on image build time, giving the possibility to load extra modules. It relies on the DIB_DRACUT_ENABLED_MODULES setting, that will accept a yaml blob with the following format:

- name: <module1>
  packages:
    - <package1>
    - <package2>
- name: <module2>
  packages:
    - <package3>
    - <package4>

By default, this element will bring lvm and crypt modules.

Also adds the ability to copy specific files into /etc/dracut.conf.d directory to allow any dracut settings to be configured. To achieve that the files to be copied need to be placed inside an specific dracut.d directory of the element.
