Removed the "User" message from the cta.proto (duplication of UserIdentity message)

Repack RetrieveRequest reported as success after mount and retrieve successful (expandRepackRequest)

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

Removed unused ex variable from 'catch (cta::exception::Exception ex)' within common/Configuration.cpp

The maintenance handler provided a negative timeout when its round too long. This
led to infinitely sleeping on a poll instead of a timeout of 10s max.

Added MEDIA_TYPE and VENDOR columns to TAPE table and upgraded xrootd-ssi-protobuf-interface to v0.29

This promotion is controlled so that only a limited number a requests
are in the
state ToExpand or Starting at any point in time. This ensures both the
availabality
of repack file requests to system while preventing an explosion of file
level requests.

Created a one-round popping from the container (algorithms) with status
switching.
  - Used for repack requests switching from pendig to to expand

Added ElementStatus to algorithms.

Implemented promotion interface in Scheduler and OstoreDb. The actual
decision is taken at
the Scheduler level. The function itself is called by the
RepackRequestManager.

Promotion is tested in a unit test.

Various code maintenance:
Switched to "using"-based constructor inheritance.
Fixed privacy of function in cta::range.

Merged RepackInfo and RepackType.
Simplifed RepackInfo to what is currently implemented.
Implmented repack related dumps.

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.

Created initial (incomplete) logging of timings for generic popping from container.

Done

We now have live (to be executed), failed and to be reported queues.
Archive jobs have all three types, retrieve jobs do not have a to be reported
queue. The RootEntry interface interface now provides the choice between the types.
All uses are currently hardcoded to LiveJobs.
