 The promise interface provides the common interface for all promise

 A promise represents an eventual outcome, which is either fulfillment (success)
 and an associated value, or rejection (failure) and an associated reason.
 
 Once in the fulfilled or rejected state, a promise becomes immutable.
 Neither its state nor its result (or error) can be modified.

-Creates a already fulfilled promise.

-```php
-$promise = new React\Promise\FulfilledPromise($value);

-Note, that `$value` **cannot** be a promise. It's recommended to use
