This included extracting missing data while popping elements from archive queue.

- Queueing into the RetrieveQueueToReportToRepackForFailure
- Reporting of the failed RetrieveJobs (add statistics + deletion of the failed sub requests)
Unit test associated : expandRepackRequestFailedRetrieve

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

Someone added xrootd in eos-citrine-depend repo which had a priority of 2. Lowering this one as people are messing with it.

repositories.

basically requiring xrootd-4.8-3 and not our 4.9.0 this is an externally
triggered problem. To fix this we can either disable protectbase yum
plugin for all our yum commands, remove the plugin, sed -i
's/protect=1/protect=0/' /etc/yum.repos.d/* in all our containers OR
enable baseprotect on our repos...
I enabled baseprotect on all our repos.

Updated the unit tests to validate the queues and requests are as expected.

Changed the reporting structures in the repack request to better handle repoting
(we will report one archive job per rearchived copy number, which is potentially
several per fSeq.

Created the getNextBatch() function for retrieve successes and partially implemented
the report function.

Also created the call in the maintenance process.

Reports can now be either "to user" or "to repack".

Renamed function to getNextRetrieveRequestToReportToRepackForSuccessBatch to match current naming convention.

The retrieve requests now carry all the information necessary to create the archive jobs.
Retrive requests carry an isRepack boolean. The distinction between repack and non-repack behaviour
is pushed as low as possible in the api (in the object store) so that client code can be more
generic. For the same reason, the
The expand repack mode (re-creation of missing tape files) is not supported yet.
Changed the represenation of copy numbers to uint32 (as this is the smalled number supported but protocol buffers).
Added ArchiveRoute::StorageClassMap and ArchiveRoute::FullMap to store archive routing in memory.
Added repack buffer base URL support, and mechanism to compute temporary copy location in disk cache.
Fixed bug in ObjectOps<>::asyncInsert();
Inplemented the path generation for repack disk storage (<BaseURL>/<VID>/<FSeq (09%d)>).

Upgraded to EOS 4.4.25-20190301013418git43576ce in order to get Elvin's new FST communication configuration where we can set the number of connections used by the FST to send commit messages to the MGM

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.
