[kchudy]

• Test migrating firewall rules to 2.0
• Provide script for migration if necessary
• Provide documentation on migrating the firewall if necessary
• Create ADR for changes in the Firewall module

For reference this is the test fixture I've used to verify if the firewall rules generated pre and post migration match: acl_pre_2_0_migration_fixture.sql
