-  The type of bucket to create. Accepted bucket types are "couchbase",
-  "ephemeral", and "memcached". The Couchbase bucket is the standard bucket
-  type. It supports data persistence, replication, caching, indexing, views,
-  and {sqlpp} queries. The Ephemeral bucket is an in-memory bucket similar to the
