Ceph kernel client now has a facility to check stats for certain
operations. One of these operations is the 'copyfrom', the
operation that is used to offload to the OSDs the copy of objects
from, for example, the copy_file_range() syscall.
This patch changes ceph/001 to add an extra check to verify that the
copies performed by the test are _really_ remote copies and not
simple read+write operations.

For the moment cross quota realms renames has been disabled in CephFS
after a bug has been found while renaming files created and truncated.
This allowed clients to easily circumvent quotas.

Test remote copy operation (CEPH_OSD_OP_COPY_FROM) with different
combinations of both object sizes and copy sizes.
Test remote copy operation (CEPH_OSD_OP_COPY_FROM) with several
combinations of both object sizes and copy sizes. It also uses several
combinations of copy ranges. For example, copying the 1st object in the
src file into:
1) the beginning (1st object) of dst file,
2) the end (last object) of dst file and
3) the middle of the dst file.
