Title: ASGARD-971 - Add robustness to handle misconfigured subnets

Subnets without a purpose can't be added to an ASG in Asgard. But this could be misconfigured outside of Asgard, or the purpose could be removed afterwards. Currently an ASG with subnets that have no purpose causes problems in Asgard. When editing the ASG or creating the next ASG in a cluster, no subnets will be associated.
When this situation arises, a warning should be displayed, zones should not be editable, and the current subnets should be copied.
