ceph: new mount option to disable usage of copy-from op
Add a new mount option 'nocopyfrom' that will prevent the usage of the RADOS 'copy-from' operation in cephfs. This could be useful, for example, for an administrator to temporarily mitigate any possible bugs in the 'copy-from' implementation. Currently, only copy_file_range uses this RADOS operation. Setting this mount option will result in this syscall reverting to the default VFS implementation, i.e. to perform the copies locally instead of doing remote object copies.
