Added a display of the state of the tape before and after each repack

Simple repack on CI

Corrected cta-admin af ls command so that it fills the superseded vid and superseded columns in the result

Replaced the map of tape files with a list as the assumption that we have one copy per copyNb is no more valid with repack.

Added a check while mounting a tape for writing : if some tape files located in the writing tape are not superseded by others,
the write session will fail.

Note: The test CatalogueTest.exist_non_superseded_files_after_fseq is supposed to fail.

cta-admin was failing due to incoherent internal data.

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

- Queueing into the RetrieveQueueToReportToRepackForFailure

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.
