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.
