Dropped stats in the callhandlers of rfio. This prevents detection of non existing files but allows ceph pools to work and all this code will anyway soon be ripped off

Replaced all calls to local io in rfio with the generic counter part defined in rfio_localio. In other terms : enabled ceph pool in rfiod

Dropped check for available space for DataPool when launching a job. This is much less interesting than in the general case as a single job can hardly fill a whole pool. On top, this check would have been very costful

Dropped the check for empty mountPoint in stagerJob as this is now valid and indicated the usage of a DataPool

constraint is enough, while for master we keep the new simplified code.

constraint violation.
Removed constraint and reworked filesDeletedProc. It is OK to
drop a DiskCopy entry with an outstanding Disk2DiskCopyJob, when
it will start the case will be handled properly.

constraint violation.
The fix is to differentiate the handling of the constraint violation
exceptions: on diskCopy, everything has to go, while on castorFile
no action is taken as the entry could have been reused. Thus the code
specifically ignoring the castorFile exceptions has been moved around
the DELETE FROM CastorFile clause.
