This commit adds the missing "order by" clause.

all containers.
Many failures were due to slow DNS name resolution by kube-dns.
To solve this I am now scanning all registered services in the namespace
and adding entries to /etc/hosts on all the `Running` containers in the
namespace. This solution is valid for both systemd and non-systemd
containers.

Following on from GitLab issue cta/CTA#371, replaced INTEGER with NUMERIC(20, 0) within oracle_catalogue_schema_header.sql

Following on from GitLab issue cta/CTA#371, replaced INTEGER with NUMERIC(20, 0) within mysql_catalogue_schema_header.sql

Changed common_catalogue_schema.sql for cta/CTA#371 'Change INTEGER columns of CTA catalogue schema to NUMERIC(20,0)'

moving core dumps to /var/log/tmp/%h-%t-%e-%p-%s.core so that they are available as artifacts for all pods AND in the log PV that has supposedly more space.

delete_instance.sh can write log to an alternate directory and not only /tmp as it may be too small for larger tests.

Adding systemd-resolved to all possible DNS intense pods to avoid Nameserver complaints for larger tests. client pod is now using systemd as well for this reason.

1 block per file and blocks >=256kB: more smaller blocks (min size). Do not mount a tape for less than 100 files.

Fixed cta/CTA#364 RdbmsArchiveFileItorImpl constructor should NOT return database connection to pool

Changes XrdSsiPb log messages from INFO to DEBUG level. Adds protobuf
messages for "cta-admin failedrequest ls".

Replaced 'catch (std::out_of_range)' within objectstore/Helpers.cpp with 'catch (std::out_of_range &)' in order to avoid the compilation error on newer compilers :catching polymorphic type ‘class std::out_of_range’ by value [-Werror=catch-value=]

Replaced 'catch (cta::exception::Exception)' within 'Configuration.cpp' by 'catch (cta::exception::Exception &)' in order to avoid 'catch-value' compilation error on newer compilers
