It was used but we probably got away thanks to compiler optimizing it out.

Added partial support for repack queueing in scheduler database,
scheduler and CLI.

No inheritance, instead have partial or full specialization based on two
template parameters.

This commit passes compilation but not linking (yet) as several
methods are still commented out.

cta-fst-gcd now reports every 10,000 files that it has considered them.  This should help us see how fast the garbage collector is

This prevented the passing of exceptions as output.
Also integrated the promise in the reporter class.

This allows better internal (in-memory) tracking, and avoid spurious
"In OStoreDB::ArchiveJob::~ArchiveJob(): will leave the job owned after destruction."
message in the logs.

This avoid getting a cassandra pacakge instead of the intended one.
Also added better logging for the eos container startup output (kubectl logs is unreliable).

The maintenance process replaces the garbage collector process. It now
runs both garbage collection and disk reports.

Extended unit test to also simulate reporter.
Fixed issue with trimming trying to trim the wrong type of queue.
Fixed report type not properly extracted when popping request for report.

Changed the lifecycle of the ArchiveRequest to handle the various
combinations of several jobs and their respective success/failures.
Most notably, the request now holds a reportdecided boolan, which
is set when decing to report. This happens when failing to archive
one copy (first failure), or when all copies are transferred (success
for all copies).

Added support for in-mount retries. On falure, the job will be
requeued (with a chance to pick it up again) in the same session
if sane session retries are not exceeded. Otherwise, the job is
left owned by the session, to be picked up by the garbage collector
at tape unmount.

Made disk reporter generic, dealing with both success and failure.
Improved mount policy support fir queueing.

Expanded information avaible in popped element from archive queues.

Added optional parameters to ArchiveRequest::asyncUpdateJobOwner() to
cover various cases.

Updated the archive job statuses.

Clarified naming of functions (transfer/report failure instead of bare
\"failure\").

Updated garbage collector for new archive job statuses.

Added support for report retries and batch reporting in the scheduler
database.

Updated obsolete wording in MigrationReportPacker log messages and error
counts.

Their poping of elements will be indifferent of number of bytes.
