Description Tejas 2021-05-07 14:44:17 UTC 
Description of problem:
   
]# ceph -v
ceph version 16.2.0-4.el8cp (987b1d2838ad9c505a6f557f32ee75c1e3ed7028) pacific (stable)

 on a 5.0 setup, I am observing a weird behaviour. Here is the scenario:
1. max_objs_per_shard=500
2. Create bucket enable versioning, and add 200k objects (no versions)
3. Set a lifecyle policy to delete all objects in 1 day.
4. "radosgw-admin bucket list"  is showing a total of 965k entries for 200k objects. And we can observe 2,3,4 delete markers for each object .

For example , taking 1 object:
"name": "obj100169",
        "instance": "C6lecpIVgvxqEGXk5WKD.URahnfi0ig",
"tag": "delete-marker",
        "flags": 7,

"name": "obj100169",
        "instance": "wCNJNFkzS7-vfQqVXTueBHanR.kQD0t",
"tag": "delete-marker",
        "flags": 5,

 "name": "obj100169",
        "instance": "Ed-SOzPBcCgT2LmpsVbdEBBK5ZMQYte",
"tag": "delete-marker",
        "flags": 5,

"name": "obj100169",
        "instance": "XTkr-0ngr9IrFucta9LSigYJ74uLYKR",
"tag": "adacbe1b-02b4-41b8-b11d-0d505b442ed4.144161.113165",
