A request contains the following informations:

• The Playable
• The target Container
• The Playback configuration, tag, callbacks, etc
• The Manager, Bucket and some meta data

Binding a request needs to be safe:

• It is started only after the lifecycle of the Manager, Bucket and the Container is started.
• If the lifecycle of the Manager, Bucket or the Container is destroyed, the request must be canceled.
• If a request is sent that is different to a previous request about the Playable, the Container or the Tag, the previous request must be canceled.
