Problem this snippet solves:
Adds support for attaching a pre-existing ASM policy when deploying on BIG-IP v11.4.0 and later (template supports BIG-IP v11.3 and later).
Fixes an issue with the associated cli script that could prevent users from importing iApp templates
Adds AFM and APM profile selection. Note: there is now a dedicated page for the v1.1.0 iApp template: https://devcentral.f5.com/codeshare/http-iapp-v110
Contains a fix for users upgrading from the legacy 11.3 variable schema.
