This pull request introduces several enhancements and adjustments to the AWS collectors and dependencies, including:

Enhanced Logging:

Added [INFO] logs for services being processed at various stages within collectors/aws/collector.js and collector_multipart.js. These logs will help track service progress, assisting in debugging and monitoring. Error Handling:

Implemented error handling for cases where specified services do not exist in the AWS SDK, logging [ERROR] messages and returning callbacks appropriately. Dependency Updates:

Updated the aws-sdk package to a newer version in package.json (from ^2.1506.0 to ^2.1692.0). This ensures compatibility with the latest AWS service updates and security improvements.
