[WORKFLOW SDK BUG] Orchestration nomenclature & Protobuf concerns bleed through to API surface

[olitomlinson]

Expected Behavior

Setting a reuse policy should be as simple and intuitive as using an enum e.g.

reuse_policy = ReuseIdPolicy.IGNORE

workflow_client.schedule_new_workflow(
    workflow=tracker_workflow,
    instance_id=str(run_id),
    input={},
    reuse_id_policy=reuse_policy  # Prevents "workflow already exists" errors
)

Actual Behavior

1. Orchestration is an underlying durabletask term, this should not bleed through to the public API
2. Protobuf concerns should not bleed through to the public API

# Create reuse policy to ignore if workflow already exists (handles race conditions)
reuse_policy = pb.OrchestrationIdReusePolicy(action=pb.IGNORE)

workflow_client.schedule_new_workflow(
    workflow=tracker_workflow,
    instance_id=str(run_id),
    input={},
    reuse_id_policy=reuse_policy  # Prevents "workflow already exists" errors
)
