Users API in Database API Reference is incomplete

[黎菁]

The api doc is lack of update attributes of user, like this :
PUT /v1.0/{accountId}/instances/{instanceId}/user/{name}
This operation will update user attributes.
request example:
{
    "user": {
        "name": "root",
        "password": "12345"
    }
}
