Public bug reported:
On Ubuntu resolute radosgw from 20.2.0-0ubuntu2 reproducibly segfaults
when an S3 request is authenticated with Keystone EC2 credentials. The
client sees "502 Bad Gateway" and systemd restarts radosgw.
This is the Keystone-backed S3 auth path. Local RGW users can work when
local auth is tried first, but a request using Keystone EC2 credentials
still crashes RGW.
This can be reproduced using the CI bundle with adaptation for resolute
and zaza tests
