/**
 *
 * Works with Queue servers.
 *
 * Testing with a selection of remote/local queueing services, including Amazon's SQS service
 * Iron.io service and beanstalkd service.
 *
 * Supported and tested queue types are:
 *
 * * [Iron.io](http://iron.io/)
 * * [Beanstalkd](http://kr.github.io/beanstalkd/)
 * * [Amazon SQS](http://aws.amazon.com/sqs/)
 *
 * The following dependencies are needed for the listed queue servers:
 *
 * * Beanstalkd: pda/pheanstalk ~3.0
 * * Amazon SQS: aws/aws-sdk-php
 * * IronMQ: iron-io/iron_mq
 *
 * ## Status
 *
 * * Stability:
 *     - Iron.io:    **stable**
 *     - Beanstalkd: **stable**
 *     - Amazon SQS: **stable**
 *
 * ## Config
 *
 * The configuration settings depending on which queueing service is being used, all the options are listed
 * here. Refer to the configuration examples below to identify the configuration options required for your chosen
 * service.
 *
 * * type - type of queueing server (defaults to beanstalkd).
 * * host - hostname/ip address of the queue server or the host for the iron.io when using iron.io service.
 * * port: 11300 - port number for the queue server.
 * * timeout: 90 - timeout settings for connecting the queue server.
 * * token - Iron.io access token.
 * * project - Iron.io project ID.
 * * key - AWS access key ID.
 * * version - AWS version (e.g. latest)
 * * endpoint - The full URI of the webservice. This is only required when connecting to a custom endpoint (e.g., a local version of SQS).
 * * secret - AWS secret access key.
 *      Warning:
 *          Hard-coding your credentials can be dangerous, because it is easy to accidentally commit your credentials
 *          into an SCM repository, potentially exposing your credentials to more people than intended.
 *          It can also make it difficult to rotate credentials in the future.
 * * profile - AWS credential profile
 *           - it should be located in ~/.aws/credentials file
 *           - eg:  [default]
 *                  aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID
 *                  aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY
 *                  [project1]
 *                  aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID
 *                  aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY
 *          - Note: Using IAM roles is the preferred technique for providing credentials
 *                  to applications running on Amazon EC2
 *                  http://docs.aws.amazon.com/aws-sdk-php/v3/guide/guide/credentials.html?highlight=credentials
 *
 * * region - A region parameter is also required for AWS, refer to the AWS documentation for possible values list.
 *
 * ### Example
 * #### Example (beanstalkd)
 *
 *     modules:
 *        enabled: [Queue]
 *        config:
 *           Queue:
 *              type: 'beanstalkd'
 *              host: '127.0.0.1'
 *              port: 11300
 *              timeout: 120
 *
 * #### Example (Iron.io)
 *
 *     modules:
 *        enabled: [Queue]
 *        config:
 *           Queue:
 *              'type': 'iron',
 *              'host': 'mq-aws-us-east-1.iron.io',
 *              'token': 'your-token',
 *              'project': 'your-project-id'
 *
 * #### Example (AWS SQS)
 *
 *     modules:
 *        enabled: [Queue]
 *        config:
 *           Queue:
 *              'type': 'aws',
 *              'key': 'your-public-key',
 *              'secret': 'your-secret-key',
 *              'region': 'us-west-2'
 *
 * #### Example AWS SQS using profile credentials
 *
 *     modules:
 *        enabled: [Queue]
 *        config:
 *           Queue:
 *              'type': 'aws',
 *              'profile': 'project1', //see documentation
 *              'region': 'us-west-2'
 *
 * #### Example AWS SQS running on Amazon EC2 instance
 *
 *     modules:
 *        enabled: [Queue]
 *        config:
 *           Queue:
 *              'type': 'aws',
 *              'region': 'us-west-2'
