implement `iso_interface` setting

Adds a new configuration option, `iso_interface`, that can be set to

add documentation for `iso_interface`

Adding a script to compile the linux binaries
Added required value for openstack_provider for rackspace example

Formatting
The mount command for a PV image that is attached to /dev/sdf is:
mount /dev/xvdf /mnt/point
while for an HVM image that is attached to /dev/sdf, its mount command is
mount /dev/xvdf1 /mnt/point
so this code enabled that
