New feature: API permission management

Dear API user:

In order to facilitate users to use API more conveniently and safely, Huobi Global introduce a new feature, which will allow users to assign permissions to each API Keys.

Changes：

1.When a new API Key is created, one or more permissions should be assigned to the API Key.

2.There are three permissions could be chosen: read-only, trade, and withdraw.

3.Only the APIs published in our official Huobi API Document could be accessed by API Keys.

4.All existing API Keys will be default with all permissions, you can change existing API Keys permission here: https://www.hbg.com/zh-cn/apikey/.

For more details about each endpoint permission: https://huobiapi.github.io/docs/spot/v1/en/
