在 Doris 中，一个 user_identity 唯一标识一个用户。user_identity 由两部分组成，user_name 和 host，其中
username 为用户名。host 标识用户端连接所在的主机地址。host 部分可以使用 % 进行模糊匹配。如果不指定 host，默认为
'%'，即表示该用户可以从任意 host 连接到 Doris。
-host 部分也可指定为 domain，语法为：'user_name'@['domain']，即使用中括号包围，则 Doris 会认为这个是一个
domain，并尝试解析其 ip 地址。目前仅支持百度内部的 BNS 解析。
+host 部分也可指定为 domain，语法为：'user_name'@['domain']，即使用中括号包围，则 Doris 会认为这个是一个

如果指定了角色（ROLE），则会自动将该角色所拥有的权限赋予新创建的这个用户。如果不指定，则该用户默认没有任何权限。指定的 ROLE 必须已经存在。
