Revert "cta/CTA#186 CTA should cope with idle database connections being dropped by the database server"

This reverts commit 1be86a70.

Refactored RdbmsCatalogue::getTapesForWriting() to be like OracleCatalogue::filesWrittenToTape()

OracleCatalogue::filesWrittenToTape() should now transparently re-connect to the database.

RdbmsCatalogue::getTapesForWriting() should now transparently re-connect to the database.

Admin commands should now transparently re-connect to the database.

Fixed the following offending method:

    RdbmsCatalogue::prepareForNewFile()

Added the following unit-test that explicitly tests for a UserError exception:

    cta_catalogue_CatalogueTest.prepareForNewFile_no_archive_routes

Done

The same variable is now used in all cases.

Added options, suppressions and re-implemented BackendVFS::AsyncLockfreeFetcher to try and make valgrind happy.

Added dump for ArchiveQueueShards.
Unit tests now pass with sharded archive queues.

Updated locking of ObjetOps in order to allow locking of sub-objects.
Make cta-objectstore-dump-object lockfree.

removing replace-str option as -L just concatenates args after the replace-str place holder. toto is not a valid rados object which prevents the objectstore cleanup.

Default now set to 10s. Note that XRD_TIMEOUTRESOLUTION must be set
<= 10s, otherwise timeout defaults to 15s.

Reduced to the minium the number of database connections used by createSameSchemaInTwoSeparateInMemoryDatabases

Now the submodule does not provide a CMakeLists.txt file, this is now
provided by the main project (eos_cta/CMakeLists.txt)

from tapeserver/daemon to common directory

Reduced usage of RetrieveQueue::dumpJobs() in general.
Removed dead code.
Added locking checks where missing.
