Add translation template for labels

[koenvu]

In some of our projects we use a language line system of:

'fields' => [
    'email' => [
        'label' => 'Email address',
        'placeholder' => '',
        'tooltip' => '',
        'help' => '',
    ],
    'password' => [
        'label' => 'Password',
        'placeholder' => '',
        'tooltip' => '',
        'help' => '',
    ],
    'submit' => [
        'label' => 'Log in',
    ],
],

This doesn't work with the current language_name functionality and would force us to manually write trans('customer.login.fields.email.label') for all fields.

This new functionality is fully backwards compatible with the old code, as long as you didn't use translation_template for custom functionality yet (highly unlikely).

Would love to hear what you think, and if you like it when you plan to release a new version.

Thanks in advance!

This would be very nice for my project as well!
