Add a views relationship handler

Ideally the user should be able to relate a view of users or any relationship providing a uid with the login_history table. For instance, if you have a view of users by username, why not add a field for user logins? Aggregating the count of this field would result in a field with total logins. This is only possible with a relationship.

/**
 * Implements hook_views_data_alter().
 */
function login_history_utility_views_data_alter(array &$data)
{
  $data['users']['login_history'] = [
    'title' => t('Logins'),
    'help' => t('Relate a user to historical logins'),
    'relationship' => [
      'id' => 'standard',
      'group' => 'Login History',
      'base' => 'login_history',
      'base field' => 'uid',
      'relationship field' => 'uid',
      'handler' => 'standard',
      'label' => t('Logins'),
      'field' => 'uid'
    ],
  ];
}
