Summary
Add a containerd config to enable EROFS snapshotter and referrer flag when IPE is enabled. This config change will only be triggered if IPE is in audit mode. When IPE is set, IPE's loader will run the acl-select-profile script to merge the base containerd config that AgentBaker or ACL sets with the EROFS config. None of the settings in the base config get overwritten.
This is a follow up PR for after the containerd2 patch enabling dmverity referrers is merged.
