Don't append '/' to path if path already ends in '/'

Corrected scheduling to wait for more files to be queued before creating ArchiveForRepack mount + Unit test

If EOS namespace current fileid for directories is < 2.5 billion,
this generates a warning on running eos-import-dirs.

If eos-import-dirs tries to inject a fileid > EOS current fileid,
it stops and throws an exception.

This option is enabled by default, and requires all metadata to match
for a directory to be removed from the failure table.

If it is disabled, it takes a more relaxed approach and checks only the
invariant metadata (file id and path)

Removes TRUNCATE FILE and disables autocommit, so the temp table is
emptied automatically after each batch of failures.

- removes SQL MERGE
- adds separate DELETE, UPDATE and INSERT steps
- DELETE and UPDATE steps are only needed for retries
  (this implies that the failure table should be purged if for
   some reason it is necessary to try again from the main table)

Corrected auto garbage collection of ArchiveRequest ToTransferForRepack (getQueueType missed one case)

Changed catch(std::out_of_range) to catch(std::out_of_range &) in order to avoid the following type of compilation error:

../CTA/common/checksum/ChecksumBlob.hpp:145:18: error: catching polymorphic type ‘class std::out_of_range’ by value [-Werror=catch-value=]
     } catch(std::out_of_range) {
                  ^~~~~~~~~~~~
cc1plus: all warnings being treated as errors

Increased the time to lock a Rados object from 300ms to 1 sec. This correction is due to CI repack error (caused by BackendRados::lockBackoff(): timeout)

Removed objectstore initialization agent after objectstore initialization (cta-objectstore-initialize.cpp)
Catched other exceptions in continuousintegration/orchestration/tests/client-ar-abortPrepare.cpp
