BES File transfer system:

the client is not stable enough. Need further work

Solution: set up a new BOINC test bed, starting from scratch, to identify the problem.

Have found out why CVMFS client failed at connecting local squid servers, needs to clean up the residue, modify the quattor template,

and redeploy CVMFS clients to all work nodes.
