Dynamic Pipeline Support Expansion

This release significantly expands support for dynamic pipelines across multiple orchestrators:

AWS Sagemaker Orchestrator: Added full support for running dynamic pipelines with seamless transition from existing settings and faster execution through direct use of training jobs. PR #4232
Vertex AI Orchestrator: Dynamic pipelines are now fully supported on Google Cloud's Vertex AI platform. PR #4246
Kubernetes Orchestrator: Improved dynamic pipeline handling by eliminating unnecessary pod restarts. PR #4261
Snapshot Execution: For Pro users, the new release enabled running snapshots of dynamic pipelines from the server with support for specifying pipeline parameters. PR #4253

Improved

Enhanced step.map(...) and step.product(...) to return a single future object instead of a list of futures, simplifying the API for step invocations. PR #4261
Improved placeholder run handling to prevent potential issues in dynamic pipeline execution. PR #4261
Added better typing for Docker build options with a new class to help with conversions between SDK and CLI. PR #4262

GCP Image Builder Regional Support

Added regional location support to the GCP Image Builder, allowing you to specify Cloud Build regions for improved performance and compliance:

Optional location parameter for specifying Cloud Build region
Uses regional Cloud Build endpoint ({location}-cloudbuild.googleapis.com) when location is set
Maintains backward compatibility with global endpoint as default
Includes input validation for location parameter

PR #4268
