Jan Grant fe33d34637 Add switch to turn on caching for debian element.
DIB_OFFLINE has wide-ranging effect. This patch adds a tunable that
only turns on the tarball-caching behaviour specifically for the
debian element.

Create an image based on Debian. We default to unstable but DIB_RELEASE
is mapped to any series of Debian.
Note that the default Debian series is `unstable`, and the default
mirrors for Debian can be problematic for `unstable`. Because apt does
not handle changing Packages files well across multiple out of sync
mirrors, it is recommended that you choose a single mirror of debian,
and pass it in via `DIB_DISTRIBUTION_MIRROR`.
Use of this element will also require the tool 'debootstrap' to be
available on your system. It should be available on Ubuntu, Debian,
and Fedora.
The `DIB_OFFLINE` or more specific `DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE`
variables can be set to prefer the use of a pre-cached root filesystem
tarball.
