This pull request adds support for ModelLifeCycle functionality in SageMaker. The key addition is a new test file that verifies the model registration process can properly handle ModelLifeCycle objects, which help track and manage the stages of a model's lifecycle (like Development, Staging, Production etc.).

The changes appear to be focused on:

  1. Model lifecycle management capabilities
  2. Testing the proper conversion and handling of model lifecycle metadata during model registration
  3. Integration with SageMaker's model registry system

The core changes involve verifying that ModelLifeCycle objects are correctly converted to the expected dictionary format when registering models, ensuring proper tracking of model stages and status throughout their lifecycle.

This enhancement provides better model governance and tracking capabilities in the SageMaker SDK.

Add unit test to verify ModelLifeCycle object integration with model.register() method. The test ensures proper dictionary conversion and parameter passing when registering models with lifecycle metadata.
