This commit adds a set of commands to monitor for enabling breakpoint debugger. This is implemented based on the walker utility for step-by-step LLB inspection. For each vertex and breakpoint, monitor calls Solve API so the user can enter to the debugger container on each vertex for inspection. User can enter to the breakpoint debugger mode by --invoke=debug-step flag. Signed-off-by: Kohei Tokunaga <ktokunaga.mail@gmail.com>
