【主档类】创建租户会员

创建会员基于用户主档信息，需确保用户记录已创建（请求参数openId必须与创建用户时的openId保持一致）
P.S. 不同租户下相同手机号将各自产生各自的租户会员记录（多个memberId），但易百会员为唯一记录（一个ebuyMemberId）

注意：为保证签名的一致性，返回报文中的content字段将以string形式的进行返回，例如：

{
	"content": {
		"userId": 1,
		"userName": "Trump"
	}
}

将返回为：

{
	"content": "{\"userId\":1,\"userName\":\"Trump\"}"
}

{
  "uuid": "20210629-ixlbyfjxuamqfrsxetovgklcrjjmsrhd",
