Restart Instance

[YunchuWang]

This pull request introduces a new orchestration restart capability to the Durable Task JavaScript SDK, along with comprehensive end-to-end tests to validate its behavior. The main changes are the addition of a restartOrchestration method on the TaskHubGrpcClient class and a new E2E test suite covering various restart scenarios, including positive and negative cases.

New orchestration restart functionality:

• Added a restartOrchestration method to the TaskHubGrpcClient class, allowing users to restart completed, failed, or terminated orchestrations with either the same or a new instance ID. The method includes input validation and detailed error handling for various orchestration states.

Comprehensive E2E test coverage:

• Added a new test file restart.spec.ts with end-to-end tests for the restartOrchestration API, covering:
  • Restarting orchestrations in completed, failed, and terminated states.
  • Restarting with the same or a new instance ID.
  • Preservation of original input data upon restart.
  • Default parameter behavior for the restartWithNewInstanceId argument.
  • Negative cases, such as attempting to restart non-existent, running, or suspended instances with the same ID, and verifying appropriate error handling.
