List available transactions given the state of the state machine

[sammydowds]

1 New Class:

• TransitionMeta which is added to the transition methods .__fsm attribute

2 New StateMachine methods:

• all_transitions, returns list of all Transitions
• available_transitions, returns list of all available Transitions based on state of the StateMachine

At first, I thought this would be way simpler. Let me know if this is not the solution you were looking for!

It looks like pytest still passes, however this is only my second PR - so I would love some feedback!
