    Replace glance_metadata check with bootable column.

    This patch adds a column to indicate if a volume is bootable or not.

    Cinder API V1 was using get.volume_glance_metadata to determine
    if a volume was bootable for translate_view.

    This is fine until you put a heavy load on the system and things
    can fall apart, particularly the backref of the glance meta is no longer
    available and the call blows up. Also this results in a bit of extra
    unnecessary data being passed around with every create and get call.
    This is especially an issue when creating hundreds or thousands of volumes.
    Even better we can now reliably create thousands of volumes.

    Fixes bug: 1192390
