debugobjects: add boot parameter default value
Impact: add .config driven boot parameter default value
Right now debugobjects can only be activated if the debug_objects
boot parameter is passed in via the boot command line.
Make this more convenient (and randomizable) by also providing
a .config method. Enable it by default. (DEBUG_OBJECTS itself
is default-off)
