Upgraded to EOS 4.4.19-1 in order to get the version of the 'file archived' garbage collector that can be configured 'on' or 'off'.  By turning the 'file archived' garbage collector 'off' we will be able to to test the MGM LRU garbage collector more easily.

Added the first version of the specification of the Catalogue::getTapeFilesForRepack() method - there's no implementation yet

RequestMessage::processTape_Ch() now calls m_catalogue.modifyTapeMediaType() and m_catalogue.modifyTapeVendor() so that 'cta-admin tape ch' now supports '--mediatype' and '--vendor'

Upgraded to EOS 4.4.18-20181211213834git95c105 in order to get a version of EOS that uses v0.29 of xrootd-ssi-protobuf-interface which provides the renewable resources option

Upgraded to EOS 4.4.18-20181211164351git06ae732 in order to get fixes for FSTs not reporting failed close calls when used with CTA and for problems with prepare permissions

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

Upgraded to EOS 4.4.17-20181204103742gitf66a3fa for added crosstalk protection between EOS/CTA instances and to have an FST that does not send the MGM close and sync::close events

Revert "Replaced the configuration of the asynchronous sys.workflow.closew.retrieve_written event with the synchronous one, i.e. sys.workflow.sync::closew.retrieve_written"

This reverts commit d591b0de.

Replaced the configuration of the asynchronous sys.workflow.closew.retrieve_written event with the synchronous one, i.e. sys.workflow.sync::closew.retrieve_written

The archive_failed and retrieve_failed events between the CTA tape server and EOS are now synchronous

Added chown daemon:root /var/eos/config to continuousintegration/docker/ctafrontend/cc7/opt/run/bin/ctaeos-mgm.sh

Corrected buildtree_runner/README.md by puttting 'sudo' in front of ./recreate_buildtree_running_environment.sh

Added the yum-plugin-versionlock package to continuousintegration/buildtree_runner/vmBootstrap/bootstrapSystem.sh

Added the manually specified cmake variable named NoAcs.  Please note that this variable currently has no effect when building the CTA rpms

DataTransferSessionTapeFullMigration and DataTransferSessionTapeFullOnFlushMigration now count the first files archived to tape as opposed to relying on the values of the archive file IDs
