Issue #, if available: N/A
Description of changes:

New Features

Training Job Email Notifications (SMTJ, SMHP)

• Added support for job notifications via email for training on the SMTJ and SMHP platforms via the NotificationManager class.
• Provided CloudFormation notification templates to allow users to deploy a stack of resources for receiving status updates.

SMHP Cluster Instance Group Scaling

• Added the scale_cluster() and get_instance_groups() functions to the SMHPRuntimeManager to allow users to scale their SMHP cluster restricted instance groups (RIGs) from the SDK.

RFT Lambda Deploy and Validation via RuntimeManager

• Added deploy_lambda() to RuntimeManager to package a local python file into zip, create/update a Lambda function, and store the resulting ARN on rft_lambda_arn.
• Added validate_lambda() method to invoke a deployed lambda with sample data from S3 to validate correctness before training.

Enhancements

• Simplified ECS infrastructure for RFT Multi-Turn and improved reliability
  • Removed Docker/ECR image push requirements
  • Switched ECS tasks to a public Amazon Linux 2023 base image
  • Improved CF stack state and virtual environment validation
  • Note: User might need to update their IAM policies to remove ECR permissions and add new SSM/EC2/CloudFormation permissions for RFT multiturn.
• Updated troubleshooting documentation to provide guidance on Bedrock deployment with permission restraints.
• Improved CloudWatchLogMonitor usability by allowing job start time resolution from platform APIs when not explicitly provided.

Bug Fixes

• Fixed evaluate() passing the incorrect training method to the RecipeBuilder to instead pass TrainingMethod.EVALUATION.
• Added an optional “recipe” flag to the “validation_config” to bypass recipe validation when needed.
