-- Deletes the specified Firewall and its FirewallStatus. This operation
-- requires the firewall\'s @DeleteProtection@ flag to be @FALSE@. You
-- can\'t revert this operation.
--
-- You can check whether a firewall is in use by reviewing the route tables
-- for the Availability Zones where you have firewall subnet mappings.
-- Retrieve the subnet mappings by calling DescribeFirewall. You define and
-- update the route tables through Amazon VPC. As needed, update the route
-- tables for the zones to remove the firewall endpoints. When the route
-- tables no longer use the firewall endpoints, you can remove the firewall
-- safely.
--
-- To delete a firewall, remove the delete protection if you need to using
-- UpdateFirewallDeleteProtection, then delete the firewall by calling
-- DeleteFirewall.
