These requests are queued in the RetrieveQueueToReportToRepackForFailure
Adapted the Sorter to be able to queue a RetrieveRequest from Repack into a queue identified by the RepackRequest's address

Renamed some status (#447 issue)
Harmonized the name of the Archive and Retrieve queues in the cta.proto file and made the changes in the C++ code

Documentation of the public methods of the sorter

Harmonized the copyNb type to uint32_t
Corrected a bug in RetrieveQueue::getContainerSummary() --> After insertion in the queue, the number of files and bytes added were equal to 0.

Queueing of Archive jobs now use the ContainerAlgorithms instead of the methods in the ArchiveQueue object
Created a base class (interface) that allows to add and remove object(s) from the ownership of an Agent (implementation : AgentWrapper) or from an AgentReference (implementation : AgentReference)

Queueing of Archive Jobs is done and unit tested
Queueing of Retrieve Requests is not completely done yet
