by Vadim Yanitskiy{fsm,vty}: add a VTY command to generate FSM state graphs
This command generates a state transitions graph for the given FSM.
The output format is DOT/Graphviz, which can be rendered using offline
or online (web) tools. It's useful for quickly getting a graphical
representation of the FSM states and their interconnections.
