Add bulk metadata transfer job management tools

Summary

Changes

Added comprehensive bulk metadata transfer functionality to the AWS IoT SiteWise MCP server, enabling users to perform large-scale import/export operations between S3 and IoT SiteWise. This includes:

• New metadata transfer tools: 5 new MCP tools for creating, managing, monitoring, and canceling metadata transfer jobs
• Bulk import schema validation: Tool to construct and validate JSON schemas for bulk import operations using Pydantic models
• Bidirectional transfer support: Import from S3 to IoT SiteWise and export from IoT SiteWise to S3
• Flexible filtering options: Support for exporting all resources or specific asset models/assets with configurable hierarchy and model inclusion
• Comprehensive error handling: Robust validation and error reporting with helpful examples and recommendations

User experience

Before: Users had no way to perform bulk metadata operations through the MCP server. They would need to manually use AWS APIs or CLI commands for each individual asset/model, making large-scale operations extremely time-consuming and error-prone.

After: Users can now efficiently:

• Create metadata transfer jobs with simple, user-friendly parameters
• Import bulk asset/model definitions from S3 JSON files to IoT SiteWise
• Export all IoT SiteWise resources or specific subsets to S3 for backup/migration
• Monitor job progress and status in real-time
• Cancel running jobs when needed
• Get structured validation errors with helpful examples when schema validation fails
