Description

As a Camel client, I need to define binding parameters in an URI that describes a from point of a Camel path. The way suggested by the documentation is not working.

Following is an example of the URI of a RabbitMQ that fails to set binding parameters:
rabbitmq://rabbitmq.dev.mycompany.net/myExchange?username=guest&password=guest&queue=myQueue&exchangeType=headers&vhost=all&autoAck=false&autoDelete=false&automaticRecoveryEnabled=true&args=arg.binding.country=CZ&args=arg.binding.type=myMessageType&args=arg.binding.x-match=all.

A short look into the code uncovers that the RabbitMQEndpointConfigurer expects the related 'args' (multi)value be stored in a map, but the URI scanner always encodes multivalues into a list with a (sub)name and a related value kept together in a single string. In turn, the whole 'args' parameter is ignored.
