Worker versioning support

[bergundy]

• Add UpdateWorkerBuildIdCompatibility gRPC call.
• proto: /temporal.api.workflowservice.v1.WorkflowService/UpdateWorkerBuildIdCompatibility
  In args: (from GO):

type UpdateWorkerBuildIdCompatibilityRequest struct {
	Namespace string `protobuf:"bytes,1,opt,name=namespace,proto3" json:"namespace,omitempty"`
	// Must be set, the task queue to apply changes to. Because all workers on a given task queue
	// must have the same set of workflow & activity implementations, there is no reason to specify
	// a task queue type here.
	TaskQueue string `protobuf:"bytes,2,opt,name=task_queue,json=taskQueue,proto3" json:"task_queue,omitempty"`
	// Types that are valid to be assigned to Operation:
	//	*UpdateWorkerBuildIdCompatibilityRequest_AddNewBuildIdInNewDefaultSet
	//	*UpdateWorkerBuildIdCompatibilityRequest_AddNewCompatibleBuildId
	//	*UpdateWorkerBuildIdCompatibilityRequest_PromoteSetByBuildId
	//	*UpdateWorkerBuildIdCompatibilityRequest_PromoteBuildIdWithinSet
	//	*UpdateWorkerBuildIdCompatibilityRequest_MergeSets_
	Operation isUpdateWorkerBuildIdCompatibilityRequest_Operation `protobuf_oneof:"operation"`
}

This call should be done to update worker buildID compatibility:

err := tc.UpdateWorkerBuildIdCompatibility(context.Background(), &temporalClient.UpdateWorkerBuildIdCompatibilityOptions{
	TaskQueue: wi[i].TaskQueue,
	Operation: &temporalClient.BuildIDOpAddNewCompatibleVersion{
		BuildID: wi[i].Options.BuildID,
	},
})
