Adds possibility to have related models in many-to-many relationship attached to the parent model by defined key values. Usually it would be related model `id`.

call:

```
$users = User::with('groups')->all()
```

laravel default:

```
$user->groups = [0 => $group];
```

New usage with keyBy:

```
class User extends Model
{
  use HasManyKeyByRelationship;

  public function groups()
  {
    return $this->hasMany(Group::class)->keyBy('id'); // can be string or callable
  }
}
```

result:

```
$user->groups = [$group->id => $group];
```

Some real life use cases
------------------------

[](#some-real-life-use-cases)

1. When you need to target order items by product id to apply order discounts.

    - Ex: discount for specific product on order total/shipping method etc
2. When you need to manipulate pivot records in mass.

    - Ex: users/groups grid where grid fields are some value in pivot record and not all pivot records exist

```
@foreach($users as $user)
  @foreach($groups as $group)
    {{$user->accesslevels[$group->id]?->level}}
  @endforeach
@endforeach
```
