Fix Python3 Errors in Azure Cloud Module

When using Python3, the exec_module function errors out with a
unsupported operand type(s) for +: 'dict_keys' and 'list'
error when adding the .keys() to a static list. Use the explicit
list function to make a list of keys and then add to the ['tags'] list.
