feat(CLI): Set progress output mode to plain if --debug is set

[gaocegege]

Description

If we run envd --debug up, the log will be flushed by the output writer like this. It is random-ordered and cannot be read.

The new debug flag logic in pkg/app/up.go should be:

+	debug := clicontext.Bool("debug")
+
+	builder, err := builder.New(clicontext.Context, config, manifest, buildContext, tag, debug)
-	builder, err := builder.New(clicontext.Context, config, manifest, buildContext, tag)
	if err != nil {
		return errors.Wrap(err, "failed to create the builder")
	}

We can use plain mode instead of auto mode here https://github.com/tensorchord/envd/blob/main/pkg/builder/builder.go#L64 if --debug flag is enabled.

func New(ctx context.Context,
-	configFilePath, manifestFilePath, buildContextDir, tag string) (Builder, error) {
+	configFilePath, manifestFilePath, buildContextDir, tag string, debug bool) (Builder, error) {
+	var mode string = "auto"
+	if debug {
+		mode = "plain"
+	}
	b := &generalBuilder{
		manifestFilePath: manifestFilePath,
		configFilePath:   configFilePath,
		buildContextDir:  buildContextDir,
-		progressMode: "auto",
+ 		progressMode: mode,
		tag:          tag,
		logger: logrus.WithFields(logrus.Fields{
			"tag": tag,
		}),
	}
