Add helm registry login command

[franpog859]

What do you want to see?

I'd benefit from being able to log into a private registry so I can install private charts in my e2e test.

I created the command myself but it'd be much cleaner if done the same way as the rest of the helm commands.

registryLoginCommand := fmt.Sprintf("helm registry login %s -u %s -p %s", cfg.RegistryServer, cfg.RegistryUsername, cfg.RegistryPassword)
proc := exec.NewProcWithVars(registryLoginCommand, vars.New().Vars(""))

var stderr bytes.Buffer
proc.SetStderr(&stderr)

_ = proc.Run().Result()
if !proc.IsSuccess() {
  return ctx, fmt.Errorf("%s: %w", strings.TrimSuffix(stderr.String(), "\n"), proc.Err())
}

I could check it out in some free time ^^ I guess it's nothing critical, @cpanato
