Description of storage options is important for S3, as one
needs to know if underlying storage is either local or
remote, and if the latter, details about it.
This relies on server-side desc statement.
$ ./bin/cqlsh.py -e "describe keyspace1;"
CREATE KEYSPACE keyspace1 WITH replication = { ... } AND
storage = {'type': 'S3', 'bucket': 'sstables',
'endpoint': '127.0.0.1:9000'} AND
durable_writes = true;
