baremetal kernel boot options make console inaccessible on ILO environments

[Robert Collins]

The default behaviour for Ubuntu is to modeset into a high res text mode, but ILO doesn't support those modes -showing 'console is in a graphical mode' if you try textcons at that point.

This can be worked around by adding 'vga=normal nomodeset' to the kernel boot options, which should be harmless on non-Ubuntu environments, so having this as a default would be very useful.

workaround: edit the template you are using or set pxe_append_params in nova.conf.

    Force textmode consoles

    Physical hardware often has console interception hardware for OOB
    monitoring/management. Prevent the kernel from switching to a graphical
    console mode so the hardware can do its job.
