Description of problem:
Split a large file into segments and upload each segment. Create a manifest file for all the segments and upload it. A HEAD on the manifest file fails with "404 Not found" error

Version-Release number of selected component (if applicable):
ceph-radosgw-10.2.1-7.el7cp.x86_64

How reproducible:
Always


Steps to Reproduce:
1. Split a file of about 1.5G into 3 parts
2. Upload each segment into the same container:
curl -v -X PUT -H "X-Auth-Token:token" -T segmentName accountURL/containerName/objectName
3. Create a manifest file with the object attribute content in json format
4. Now upload the manifest file with the query parameter: ?multipart-manifest=put
curl -v -X PUT -H "X-Auth-Token:token" "accountURL/containerName/StaticLargeFileName?multipart-manifest=put" -T ./manifest.json
5. Do a list to check if the SLO file is uploaded
6. Do a HEAD on the SLO file

Actual results:
A HEAD or GET on the SLO object fails even though we can list the file in the container:

# swift -A http://rgw:8080/auth/1.0 -U testuser:swift -K 'm00APyUFWGcWE4fMxOn6pmaT9OqZcpTvCcTVbbCv' list slo-container
big.txt
segment_aa
segment_ab
segment_ac

# curl -v -X HEAD -H "X-Auth-Token: Axxxxx" -L "http://rgw:8080/swift/v1/slo-container/big.txt"

> HEAD /swift/v1/slo-container/big.txt HTTP/1.1
> User-Agent: curl/7.29.0
> Host: rgw:8080
> Accept: */*
> X-Auth-Token:
> 
< HTTP/1.1 404 Not Found
< X-Trans-Id: tx00000000000000000001b-00574568b7-102e-default
< Content-Length: 9
< Accept-Ranges: bytes
< Content-Type: text/plain; charset=utf-8

< 

Whereas a HEAD on the segments work.  

Expected results:
We should be able to access the SLO object
