Downgraded redundant messages to DEBUG.

Renamed CHECHER_TAPES_FOUND to CHECKER_TAPES_FOUND in all the code (4 instances).

-Further preparations for tableView. The current code is a very general draft and makes not much sense yet
-Introducing a legend right to the treemap

using the unprivileged uid.
Also modified the DiskPoolQuery test to include a run as the unprivileged user.

user without CUPV privileges; the working path is created with
ACLs that allow that user to write.
The provided default is dteam001:cg.

This changeset also includes the following changes:
- CnsHelper has been merged into RequestHelper
- JobRequestHandler has been renamed to OpenRequestHandler and
  is the ancestor class for all the open-oriented request handlers.
- Many misleading methods (e.g. jobOriented, preHandle) have been dropped
  to have a cleaner code base (still some cleaning would be beneficial...).
- The selectCastorFile method (and PL/SQL procedure) has been
  changed to group more operations, and it now gets the subrequest ID and
  the fileClass' classid attribute.

Added a classId attribute to FileClass and populate it in the HSM tools.

Removed, these files are either no longer relevant to CASTOR2 or use PL/SQL calls which no longer work. Instead of repairing the scripts (broken for a long time), we'll wait for someone to complain first and then redo them.

Fixed system generated constraint name on the status_number column of the vmgr_tape_status_code table

Replaced exit call with a lower level one as it triggered the cleanup section (END) of the perl library from the child process in the testsuit wrapper.

Added a new return argument to the Cns_openx call to indicate whether the call resulted in the creation of a new file or not

Only log the last 5 digits of the python thread id so that we do not exceed the length expected by some other components

  - fixed the hosts used by command lines to connect to the transfer manager daemon (they were wrongly using the jobmanager host)
  - better exception handling in case of entry not found in the config file
  - avoid using JobManager entries of the config file. The involved entries have been duplicated so that the cleanup is easier when the jobManager goes

Reintroduced the call to dropsegs, this provides backwards compatibility with 2.1.10 making the upgrade/transition process smoother

-ViewNode has explicit values now. That reduces a lot of potential confusion about what information is contained in ViewNode
-renaming imagemap.html to treemap.html, preparing to split treemap.html template in order to reuse it for table view
