Update the host containers for 1.20.0

[KCSesh]

Description of changes:
Closes #3950

Update the admin and control host containers to bottlerocket-admin-container v0.11.8 and bottlerocket-control-container v0.7.12. Also add migrations move to these versions on upgrade.

Testing done:
Using an EC2 instance with the aws-k8s-1.29 variant, I successfully tested the following scenarios:

• - Bottlerocket v1.19.5 can be upgraded into Bottlerocket v1.20.0 and uses the new host container images.

After upgrade: 
bash-5.1# apiclient get settings.host-containers
{
  "settings": {
    "host-containers": {
      "admin": {
        "enabled": true,
        "source": "328549459982.dkr.ecr.us-west-2.amazonaws.com/bottlerocket-admin:v0.11.8",
        "superpowered": true,
        "user-data": "<removed>"
      },
      "control": {
        "enabled": true,
        "source": "328549459982.dkr.ecr.us-west-2.amazonaws.com/bottlerocket-control:v0.7.12",
        "superpowered": false
      }
    }
  }
}

bash-5.1# cat /var/lib/bottlerocket/datastore/current/live/os/pretty_name
"Bottlerocket OS 1.20.0 (aws-k8s-1.29)"

• - A system upgraded from 1.20.0 can be rolled back to Bottlerocket v1.19.5 and revert to using the old host container images.

After Rollback: 
[ec2-user@admin]$ apiclient get settings.host-containers
{
  "settings": {
    "host-containers": {
      "admin": {
        "enabled": true,
        "source": "328549459982.dkr.ecr.us-west-2.amazonaws.com/bottlerocket-admin:v0.11.7",
        "superpowered": true,
        "user-data": "<removed>"
      },
      "control": {
        "enabled": true,
        "source": "328549459982.dkr.ecr.us-west-2.amazonaws.com/bottlerocket-control:v0.7.11",
        "superpowered": false
      }
    }
  }
}
bash-5.1# cat /var/lib/bottlerocket/datastore/current/live/os/pretty_name
"Bottlerocket OS 1.19.5 (aws-k8s-1.29)

• - A new Bottlerocket v1.20.0 image uses the new host container images.
