Convert all HTML doc to RST

The motivation for this conversion is to have DevStack's docs be
generated using a more familair workflow for OpenStack projects, using
Sphinx.

Changing from raw HTML to RST will also make it easier to contribute
more documentation, as well as making edits less of a hassle.

The majority of the work was done by using Pandoc to convert from HTML
to RST, with minor edits to the output to remove errors in Sphinx.

+USB Boot: Undoable Stack Boot
+=============================
+
+Boot DevStack from a USB disk into a RAM disk.
+
+Prerequisites
+-------------
+
+Hardware
+~~~~~~~~
+
+This guide covers the creation of a bootable USB drive. Your computer
+BIOS must support booting from USB and You will want at least 3GB of
+RAM. You also will need a USB drive of at least 2GB.
+
+Software
+~~~~~~~~
+
+Ubuntu 11.10 (Oneiric Ocelot) is required on host to create images.
+
+Installation bit blasting
+-------------------------
+
+Set Up USB Drive
+~~~~~~~~~~~~~~~~
+
+-  Insert the USB drive into the computer. Make a note of the device
+   name, such as ``sdb``. Do not mount the device.
+-  Install the boot system:
+
+   ::
+
+       tools/build_usb_boot.sh /dev/sdb1
+
+   This calls tools/build\_ramdisk.sh to create a 2GB ramdisk containing
+   a complete development Oneiric OS plus the OpenStack code checkouts.
+   It then writes a syslinux boot sector to the specified device and
+   creates ``/syslinux``.
+
+-  If desired, you may now mount the device:
+
+   ::
+
+       mount /dev/sdb1 /mnt/tmp
+       # foo
+       umount /mnt/tmp
+
+Now `return <ramdisk.html>`__ to the RAM disk Guide to kick off your
+DevStack experience.
