Data disk is an important feature for instances and images, this
patch implements the basic functionality of it. More work needs
to be done to make it friendly to users. Docs has pointed out
current limitation.
Also update dependencies because this feature requires new code in
tencentcloud go sdk.
Instance tags are useful, our customer asks us to support it in packer as
well, to enable them to identify the purpose of the instance, even the
instance runs in a very short time.
