Comment 7 for bug 1838858

I've verified that AIO GC is working on bionic. First, I configured radosgw with:
rgw gc obj min wait = 5
rgw gc processor period = 60
rgw gc processor max time = 60

...and then tested with the Hot Sauce S3 tool, configured to create 100 10MB objects and
then request deletion, triggering the GC code:
./hsbench -a $akey -s $skey -u http://127.0.0.1:70 -z 10MB -n 100 -t 2 -b 1 -m ipd

In another window, I watched the GC list and saw that it grew when deletion was requested, and
indeed evicted objects until the count was once again 0.
