Fixing problem with comparing char with integer using the <>
operator.  This appears to be happening with some
version(s)/configurations of PostgreSQL but not all.

Added NB_EMPTY_TAPES, NB_DISABLED_TAPES, NB_FULL_TAPES and
NB_READ_ONLY_TAPES columns to getTapePools() query.

The catalogue is now only queried for the tapes of interest.

Renamed local variable vid_to_tapeinfo to vid_to_logical_library.

Added catalogueVidToLogicalLibraryTime timing metric to
'In Scheduler::getQueuesAndMountSummaries(): success.' log message.

Replaced Catalogue::getAllTape() with getVidToLogicalibrary()
because only the logical library was needed by the caller.

[scheduler] Scheduling now considers ArchiveForRepack and ArchiveForUser as two distinct types of mount

(issue https://gitlab.cern.ch/cta/operations/-/issues/150)

[scheduler] The Archive min request age is now taken into account for both type ArchiveForUser and ArchiveForRepack mounts

[tapeserver] In the case the DiskWriteTask for a file fails, the log contains its size and its checksumblob

Fixed bug in previous commit by returned xrootd-ssi-protobuf-interface sub-module to it's original commit

[cta-admin] Corrected the showqueues command in the case ArchiveForUser and ArchiveForRepack exist for the same tapepool

Fixed.
