Issue #3419129: Major refactor of ConnectionFactory and RabbitmqServiceProvider

Changes

• Refactor RabbitmqServiceProvider to remove dynamic ConnectionFactory in favour of a single rabbitmq.connection.factory service
• Refactor ConnectionFactory to work more like a factory should. New create method takes $key parameter and returns AMQPStreamConnection|AMQPSSLConnection
• Add QueueFactoryFactory to produce the dynamic QueueFactory services.
• Type hinting and constructor property promotion inline with the changes proposed to the min requirements for 4.x in !42 (merged)
