The AsDebugJSON method (used only for a LocalAPI debug call) always needed to be updated whenever a new controlknob was added. We had a test for it, which was nice, but it was a tedious step we don't need to do. Use reflect instead. Updates #14788 Change-Id: If59cd776920f3ce7c748f86ed2eddd9323039a0b Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
