Check why and add dependency if needed.

It can allow users to add their own "pending" handlers using the factory.

When executing the command, the "Processing actions..." is displayed twice.

Right now Events handler can only handle GenericEvent, should be able to handle any type of event

Maybe using travis ?

Add a handler to launch a command

PendingAction entity should have creation_date, process_date.

An action should be checked if it's not processed before processing it.
Use case :

• Command 1 gets a list of actions
• Command 1 process actions
• Command 2 is launched, gets same list of actions
• Command 2 process actions
• Command 1 should check if action about to be processed is not processed by command 2
