We have a race condition:
1. RGW client #1: requests an object be deleted.
2. RGW client #1: sends a prepare op to bucket index OSD #1.
3. OSD #1: prepares the op, adding pending ops to the bucket dir entry
4. RGW client #2: sends a list bucket to OSD #1
5. RGW client #2: sees that there are pending operations on bucket
dir entry, and calls check_disk_state
6. RGW client #2: check_disk_state sees that the object still exists, so it
sends CEPH_RGW_UPDATE to bucket index OSD (#1)
7. RGW client #1: sends a delete object to object OSD (#2)
8. OSD #2: deletes the object
9. RGW client #2: sends a complete op to bucket index OSD (#1)
10. OSD #1: completes the op
11. OSD #1: receives the CEPH_RGW_UPDATE and updates the bucket index
entry, thereby **RECREATING** it
Solution implemented:
At step #5 the object's dir entry exists. If we get to beginning of
step #11 and the object's dir entry no longer exists, we know that the
dir entry was just actively being modified, and ignore the
CEPH_RGW_UPDATE operation, thereby NOT recreating it.

dpdk library will create threasds as many as bit 1 number in
ms_dpdk_coremask and the thredas num should be equal ms_async_op_threads+1,
by ceph default confiuration,ms_async_op_threads =3,ms_dpdk_coremask =1,
so dpdk library can't create enough threads for dpdk workers. the sytem
will stuck at NetworkStack::start().so set ms_dpdk_coremask default 0xF.
and add assert to comapre the two configurations.

When generating random bucket name and object name during
loadgen processing, RGW will crash. The reason is calling
"gen_rand_alphanumeric" with "cct = NULL".

These two options currently share the same value and I have no particular
preference, but using osd_backfill_retry_interval for the specific scenario
gives us more flexible choices.
