This version of EOS should not double enqueue archive jobs in the
event that there are problems communicating with the CTA frontend.

The older styled add/remove by bulk are now sharing the access to object with heartbeat.
They should be more efficient. They are used for popping from queue and reporting jobs are done,
in the tape server.

This version of EOS has two fixes:

This version of EOS fixes the problem where stagerrm was removing
disk copies from the EOS namespace but was not removing the
physical files from the FSTs.

This version of EOS fixes the problem where the crashing of a tape
server whilst was creating a disk replica would cause the FST to
ask the MGM to completely remove the EOS file from the EOS
namespace, in other words dataloss.
