[Feature] XrootD do not follow symlink and leave original file intact

[juztas]

Moving from mailing list to git issue. In case of directory structure like this:

/store/data/foo.root
/store/newdata/foo.root -> (symlink) to /store/data/foo.root

rm cmd rm /store/newdata/foo.root will delete symlink, but it will not follow symlink. Meaning file /store/data/foo.root will remain intact.

In XRootD (mainly we use davs) removing the symlink will follow it, and will delete the file too (gfal-rm davs://...). It would be nice to have a flag, which tells xrootd not to follow symlink and leave origin file intact.
