This reverts commit edf98416.

docker/ctafrontend/cc7/opt/run/bin/init.sh now installs the standard oracle-instantclient19.3-sqlplus rpm instead of the CERN version

Revert "Top CMakeLists.txt now explicitly lists all the REQUIRED components to be found by cmake/Findoracle-instantclient.cmake"

This reverts commit 0ee95f93.

Modified Findoracle-instantclient.cmake to explicitly look for libocci.so.19.1 because the oracle-instantclient19.3-devel rpm does not create the symbolic link /usr/lib/oracle/19.3/client64/lib/libocci.so

Top CMakeLists.txt now explicitly lists all the REQUIRED components to be found by cmake/Findoracle-instantclient.cmake

- Added tool to drop from the CTA catalogue all CASTOR tapes from a given tapepool.
  This tool makes use of a temporary table and an additional PL/SQL procedure
  in order to perform efficient bulk operations in the CTA catalogue.
- Made tapepool insertion idempotent.
- Updated documentation.

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

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

Should be archiving a different file for every xrdcp. Need to add some comments as it starts to be really really bad...

Resolve "Handle the ABORT_PREPARE workflow event in CTA" and #533

Closes #533 and #252
