Use Vault as an IAM service. This is intended to be managed through the versitygw admin commands similar to the internal iam service. This uses the kv-v2 key/value secrets storage, and uses access key for the key and stores the JSON serialized account data as the value. This currently only supports roleid/rolesecret or root token authentication methods to Vault.
