Feature to find active subscriptions for a user

[6ichem]

i have been using this feature for a while through extending the main PlanSubscription model on my project but I thought it's a necessary feature to have in the original package since we have a similar feature that shows expired and so on.

Usage example:
$activeSubscriptions = app('rinvex.subscriptions.plan_subscription')->ofSubscriber($user)->findActive()->get();

@Fayozjon this PR wasn't tagged in any release yet, so to use it you need to checkout the develop branch until its tagged. So basically it works, but it exists only on the develop branch so far.
