files for cta-tape-label.

Add standalone command line tool cta-tape-label.

Command mount, label, umount the tape pointed by VID option. Tape drive
and library parameters used from /etc/cta/TPCONFIG file and catalogue
parameters from /etc/cta/cta-catalogue.conf.
To be labelled the tape must be present in the catalogue and must be
empty.
By default the tool labels the tape with enabled logical block protection
if drive supports such mode. For non-blank tapes command checks previous tape
label and label only if the old label is the same or match to the label in the
command line oldLabel option. To skip label checks for non-blank tapes --force
option could be used.

Moved catalogue/FileSizeMismatch.hpp to common/exception/FileSizeMismatch.hpp because it is so generic

Replaced the deprecated XrdClientUrlInfo by the XrdCl::URL object that is used for extracting a path of a file from a Xrootd URL

The gRPC protobuf will be shared by EOS, CTA and CERNBox, so it needs to
go in its own submodule.

Added the ArchiveForRepack mountType to the Drive reporting
Transformed the DataTransferSession::mountTypeToString() to add the ArchiveForRepack mountType, transformed the normal "Archive" into "ArchiveForUser"

Update cta::Catalogue::tapeMountedForRetrieve and
cta::Catalogue::tapeMountedForArchive to increase read/write
mount counts.

Added some unit tests to test all garbage collection of all type of Retrieve Requests (ToTransferForUser, ToReportToUser, ToReportToRepackForSuccess, ToReportToRepackForFailure)

Honoured the individual Retrieve garbage collection for jobs ToReportToRepackForSuccess and ToReportToRepackForFailure
