Client verification script should be able to populate buckets automatically
to get a good baseline for comparing similar client-created buckets against.
A yaml blueprint provides a reasonable structure to use to populate objects
and should also be easy enough for a human to follow to create test buckets
from a client.
Updates client verification tool to accept multiple bucket names on the
command line and dump information for each in case we need to test different
buckets.
After testing that a client works with an S3-like object store, use this
tool to print out information about the bucket and objects uploaded to
verify that the client worked correctly.
