        # Creates a Subnet with the CIDR block you specify.
        #
        # ==== Parameters
        # * vpcId<~String> - The ID of the VPC where you want to create the subnet.
        # * cidrBlock<~String> - The CIDR block you want the Subnet to cover (e.g., 10.0.0.0/16).
        # * options<~Hash>:
        #   * AvailabilityZone<~String> - The Availability Zone you want the subnet in. Default: AWS selects a zone for you (recommended)
        #
        # === Returns
        # * response<~Excon::Response>:
        # * body<~Hash>:
        # * 'requestId'<~String> - Id of request
        # * 'subnet'<~Array>:
        # * 'subnetId'<~String> - The Subnet's ID
        # * 'state'<~String> - The current state of the Subnet. ['pending', 'available']
        # * 'cidrBlock'<~String> - The CIDR block the Subnet covers.
        # * 'AvailableIpAddressCount'<~Integer> - The number of unused IP addresses in the subnet (the IP addresses for any stopped 
        #   instances are considered unavailable)
        # * 'AvailabilityZone'<~String> - The Availability Zone the subnet is in
        # * 'tagSet'<~Array>: Tags assigned to the resource.
        # * 'key'<~String> - Tag's key
        # * 'value'<~String> - Tag's value
        #
