Chris Jones f093d4d38d Fix troubleshooting override.
We can now actually override the $TROUBLESHOOT environment variable in
ramdisks, by not declaring it as readonly. Yay for insufficient
end-to-end testing.

This is the ramdisk element.

Almost any user building a ramdisk will want to include this in their build, as it triggers many of the vital functionality from the basic diskimage-builder libraries (such as init script aggregation, busybox population, etc).

An example of when one might want to use this toolchain to build a ramdisk would be the initial deployment of baremetal nodes in a TripleO setup. Various tools and scripts need to be injected into a ramdisk that will fetch and apply a machine image to local disks. That tooling/scripting customisation can be easily applied in a repeatable and automatable way, using this element.

See the top-level README.md of the project, for more information about the mechanisms available to a ramdisk element.
