Keystone installation from source

Makes use of new gen-source-tar script to provide a source based
keystone image.

This patch introduces a new concept of a .buildinfo file, which provides
variables specific to the image being built which cannot be defaulted in
a generic way, at least until the build script is overhauled. This file
is sourced before the .buildconf which still leaves everything
customisable by the user.
