Add monitoring configuration to emr create-cluster

[justinmae]

Description

Add support for the --monitoring-configuration parameter to the emr create-cluster command, enabling users to configure CloudWatch logging for EMR clusters through the CLI.

Motivation

This change exposes an existing EMR API feature (MonitoringConfiguration) through the AWS CLI, allowing users to configure cluster-level CloudWatch logging without needing to use the AWS SDK or Console.

Changes

• Added MONITORING_CONFIGURATION_SCHEMA to argumentschema.py
• Added MONITORING_CONFIGURATION help text to helptext.py
• Integrated --monitoring-configuration parameter in createcluster.py
• Added unit test test_create_cluster_with_monitoring_configuration

Testing

• Unit tests pass locally
• Test validates parameter parsing and API call structure
• No changes to botocore or service models required

Example Usage

aws emr create-cluster \
  --release-label emr-7.11.0 \
  --instance-groups InstanceGroupType=MASTER,InstanceType=m5.xlarge,InstanceCount=1 \
  --monitoring-configuration '{
    "CloudWatchLogConfiguration": {
        "Enabled": true,
        "LogGroupName": "MyLogGroup",
        "LogStreamNamePrefix": "MyPrefix",
        "EncryptionKeyArn": "arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012",
        "LogTypes": {
            "STEP_LOGS": ["STDOUT", "STDERR"],
            "SPARK_DRIVER": ["STDOUT"],
            "SPARK_EXECUTOR": ["STDERR"]
        }
    }
}'
