Decorator to decorate entry_point handlers to avoid to enrty a conversation if there's another one going on

[RememberTheAir]

How to do this? Check for "data" in the user's user_data

[RememberTheAir]

PROBLEM: the decorator, if it detects the "data" key in the user_data dict, should send a message and return the current status of the conversation we are currently in

How to do that? Possible solutions:

• we need to start to track the conversation status returned by handlers
• we check it by inspecting the dispatcher for some value
• ???

The decorator approach doesn't work: as soon as the dispatcher sees that another conversation's entry_point is triggered, it will end the ongoing one and start the triggered conversation

Possible solution: every conversation should register an handler that will catch all the other conversation's entry_point
