SQS and fallback subscription consumer

[deguif]

Setting receive-timeout when launching consume command does not work anymore for SQS consumer.

The SqsContext::createSubscriptionConsumer() method throws a SubscriptionConsumerNotSupportedException exception which leads to the FallbackSubscriptionConsumer::consume() method being called, and receiveNoWait() is called on the SqsConsumer

This make the AWS bill very high.
