[Accel-config] [PATCH 3/4] accel-config: Add "forced" option to load-config command

Add forced disabling of devices option as a convenience. Disabling of
devices also disables wqs so users can use different configuration files
without having to manually disable enabled devices and wqs before
reconfiguring. The option is -f, forced=true
