downburst: Decrease disk size to 100GB

The first VPS on every VPSHOST runs off the VPSHOST root drive.  Because
of this, the root drive is filling up due to the addition of another OSD
drive: https://github.com/ceph/teuthology/pull/1099

This not only results in nagios alerts but could also result in needless
job failures.  OSD drives/partitions are already only 100G on smithi so
this should be fine.
