Make the verbose-mode ("-v") UI the default UI for src action exec

[mrnugget]

After #223 and #118 we decided that we should remove the default UI and switch to the verbose-mode UI of src action exec by default.

The reason for that is that the currently-default UI has a big limitation we can't overcome: it only shows as many repositories as you have lines in the terminal. If you have less lines, we can't show you better progress.

Hi @mrnugget , I don't know if this is the right issue to ask for the first question but I hope it would be okay with you:

1. I found from this doc that there are src actions exec (plural on action) and src action exec. Are they referring to different features?
2. For this particular issue, would it be okay to just override the value of *verbose to true in the beginning of the handler creation?

Thank you very much in advance 🙂

1. I found from this doc that there are src actions exec (plural on action) and src action exec. Are they referring to different features?

Yep. They're aliases:

src-cli/cmd/src/actions.go

Lines 27 to 36 in 3b9ea70

	flagSet := flag.NewFlagSet("actions", flag.ExitOnError)
	handler := func(args []string) error {
	actionsCommands.run(flagSet, "src actions", usage, args)
	return nil
	}
	// Register the command.
	commands = append(commands, &command{
	flagSet: flagSet,
	aliases: []string{"action"},

For this particular issue, would it be okay to just override the value of *verbose to true in the beginning of the handler creation?

No. Verbose should still be available — to have an effect now or in the future. The UI should simply not be dependent on the verbose flag.

Off the top of my head, I think the first step would be to remove this and the whole terminal UI:

https://github.com/sourcegraph/src-cli/blob/master/cmd/src/actions_exec.go#L256-L258

Then we want the actionLogger to output progress without the -v flag, which means we need to remove the if a.verbose checks here:
