        # Allocate an eip IP address.
        #
        # ==== Notes
        # The new eip Ip address would be avalable
        # The allocated eip Ip address can only associate to the instance of the vpc in the same region
        # Now the eip can support ICMP,TCP,UDP
        # ==== Parameters
        # * server_id<~String> - id of the instance
        # * allocationId<~String> - id of the EIP
        # ==== Returns
        # * response<~Excon::Response>:
        #   * body<~Hash>:
        #     * 'EipAddress'<~String> - the allocated eip address
        #     * 'AllocationId'<~String> - the instance id on the public ip
        #     * 'RequestId'<~String> - Id of the request
