示例1: assignReservedContainer

/**
* Called when this application already has an existing reservation on the
* given node. Sees whether we can turn the reservation into an allocation.
* Also checks whether the application needs the reservation anymore, and
* releases it if not.
*
* @param node
* Node that the application has an existing reservation on
