Send custom parameters in bootloader to GRUB_CMDLINE

Depending on the types of deployment (security, nfv...) some extra
kernel flags are needed on the images. This change exposes the
DIB_BOOTLOADER_DEFAULT_CMDLINE parameter, defaulting to the
existing 'nofb nomodeset vga=normal', that will allow to modify
these boot params.

* ``DIB_GRUB_TIMEOUT`` sets the ``grub`` menu timeout. It defaults to
5 seconds. Set this to 0 (no timeout) for fast boot times.
* ``DIB_BOOTLOADER_DEFAULT_CMD_LINE`` sets the CMDLINE parameters that
are appended to the grub.cfg configuration. It defaults to
'nofb nomodeset vga=normal'
