Re-implement UseLocalStackOnly feature

[EronWright]

The Stack has a feature UseLocalStackOnly that, if true, prevents the system from creating new stacks in the backend. See #186.

The Workspace API has a stacks field to populate the workspace with stacks, and invokes the RPC layer to upsert each stack. Seems we must plumb a flag to support this.

Added to epic #586

This feature is already implemented and initialization will fail.

This is where we create the Workspace object:

pulumi-kubernetes-operator/operator/internal/controller/pulumi/stack_controller.go

Lines 1165 to 1168 in d52dbe7

	wss := &autov1alpha1.WorkspaceStack{
	Name: sess.stack.Stack,
	Create: ptr.To(!sess.stack.UseLocalStackOnly),
	}

Where the workspace controller talks to the agent:

pulumi-kubernetes-operator/operator/internal/controller/auto/workspace_controller.go

Lines 256 to 261 in d52dbe7

	l.V(1).Info("Creating or selecting a stack",
	"create", stack.Create, "secretsProvider", stack.SecretsProvider)
	if _, err = wc.SelectStack(ctx, &agentpb.SelectStackRequest{
	StackName: stack.Name,
	Create: stack.Create,
	SecretsProvider: stack.SecretsProvider,

In the agent code where we do not create the stack if it doesn't exist:

pulumi-kubernetes-operator/agent/pkg/server/server.go

Lines 186 to 197 in d52dbe7

	func (s *Server) SelectStack(ctx context.Context, in *pb.SelectStackRequest) (*pb.SelectStackResult, error) {
	if in.StackName == "" {
	return nil, status.Error(codes.InvalidArgument, "invalid stack name")
	}
	stack, err := func() (auto.Stack, error) {
	stack, err := auto.SelectStack(ctx, in.StackName, s.ws)
	if err != nil {
	if auto.IsSelectStack404Error(err) {
	if !in.GetCreate() {
	return auto.Stack{}, status.Error(codes.NotFound, "stack not found")
	}
	return auto.NewStack(ctx, in.StackName, s.ws)

I have manually tested that this feature works.
