       This method returns a list of the reserved instance offerings currently available for
       purchase. The arguments allow you to filter the offerings according to a variety of
       filters.

       All arguments are optional. If no named arguments are used, then the arguments are treated
       as Reserved Instance Offering IDs.

        -reserved_instances_offering_id  A scalar or arrayref of reserved
                                          instance offering IDs

        -instance_type                   The instance type on which the
                                          reserved instance can be used,
                                          e.g. "c1.medium"

        -availability_zone, -zone        The availability zone in which the
                                          reserved instance can be used.

        -product_description             The reserved instance description.

                                          VPC)"

        -instance_tenancy                The tenancy of the reserved instance
                                          offering, either "default" or

       The returned objects are of type VM::EC2::ReservedInstance::Offering

       This can be combined with the Offering purchase() method as shown here:

        @offerings = $ec2->describe_reserved_instances_offerings(

                  'product-description' =>'Linux/UNIX',
                  'duration'            => 31536000,  # this is 1 year
                  });
        $offerings[0]->purchase(5) and print "Five reserved instances purchased\n";

   $id = $ec2->purchase_reserved_instances_offering($offering_id)
   $id = $ec2->purchase_reserved_instances_offering(%args)
       Purchase one or more reserved instances based on an offering.

       Arguments:

        -reserved_instances_offering_id, -id -- The reserved instance offering ID
                                                to purchase (required).

        -instance_count, -count              -- Number of instances to reserve
                                                 under this offer (optional, defaults
                                                 to 1).

       Returns a Reserved Instances Id on success, undef on failure. Also see the purchase()
       method of VM::EC2::ReservedInstance::Offering.
