The bootloader element now has variable
DIB_BOOTLOADER_VIRTUAL_TERMINAL to customize or suppress the
console=tty0 kernel argument.
This is proposed to allow console=tty0 to be removed entirely as it is
causing significant performance degredation in DPDK environments.

Currently, the serial console is hardcoded to ttyS0 in the bootloader
element. This is a challenge for users that want to build images for
some baremetal servers. Supermicro servers, for example, use ttyS1 for
the serial over lan interface.
This patch adds a new environment variable DIB_BOOTLOADER_SERIAL_CONSOLE
that can be set to override the default.

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.
