bootconfig is a new feature that appends scripts onto the initrd, and the kernel executes the scripts as an extended kernel command line. Need to add tests to test that the happened. To test the bootconfig properly, the initrd needs to be updated and the kernel rebooted. ktest is the perfect solution to perform these tests. Add a example bootconfig.conf in the tools/testing/ktest/examples/include and example bootconfig scripts in tools/testing/ktest/examples/bootconfig and also include verifier scripts that ktest will install on the target and run to make sure that the bootconfig options in the scripts took place after the target rebooted with the new initrd update.
