Public bug reported:
The "radosgw-admin bucket limit check" command has a bug in octopus.
Since we do not clear the bucket list in RGWRadosUser::list_buckets()
before asking for the next "max_entries", they are appended to the
existing list and we end up counting the first ones again. This causes
duplicated entries in the output of "ragodgw-admin bucket limit check"
This bug is triggered if bucket count exceeds 1000 (default
max_entries).
