Subject: [PATCH] Modify struct-markdown generator code to work from different
 projct roots Modify makefile to call generate code properly, setting project
 root. 'make generate' now avoids deleting website code generated in the
 packer plugin sdk. For now it will be maintainers' responsibility to
 regenerate this docs code from the packer plugin sdk every release, and
 commit it to these folders manually. remove boot command generator code
