Changed the time interval between two polls on a VDQM request by the tapegatewayd daemon from 10 minutes to 30 seconds.  The tapegatewayd daemon polls a VDQM request in order to determine whether or not the request has been lost.

Corrected the version number of the database script responsible for creating the VMGR database from scratch.

Better implementation of delete CastorFile using foreign key constraints (possible now that they are not deferred anymore)

Removed the second and therefore superfluous filesCount parameter from the WORKER_MIGRATION_VMGR_UPDATE log message of the tapegatewayd daemon

Removed two surplus TAPEBRIDGE_SENT_FILESTOMIGRATELISTREQUEST="Sent FilesToMigrateListRequest to client" logs from the tapebridged daemon.  This message is now logged only once per messaeg sent to the client.

Randomize order in which the potential sources of d2d copies are given so that laod is better shared

Some fixes + extar logging on rebalancing. In particular, rebalance only online hardware that is in production or readonly

Improved implementation of the draining, so that it starts quick. This included added a new DB job : drainRunner that is independant of the drainManager one

Fixed handling of case where disk2diskCopyStart raises an error. The key is to know that raise_application_error does an implicit rollback.

Fixed oracle statement leading to think there were several svcClasses attached to one diskserver when it was not the case

Remove autodelete option from the draining comment. This option was useless, as it was kind of enabled even if not set. The trick was that DB triggers are checking the number of copies of files and were anyway dropping the drained copies, even if it was not done by the tool itself

In case of error when starting the job, put it back to the local queue first before telling transfermanager, so that we do not lose it in case transfermanager times out

Take into account the case where the source of a d2d is already running by the time the destination is added to the transfermanager's queue

Sorted the contents of the .gitignore file and added some "stk" and "nostk" artifacts that need to be ignore, for example "tape/mounttape-nostk".
