Custom cluster domain

- EKS 1.23
- BottleRocket AMIs
- v1.1.0

We have a cluster with a customized cluster domain name. The agent insists on connecting to https://brupop-apiserver.brupop-bottlerocket-aws.svc.cluster.local/bottlerocket-node-resource which does not resolve in that cluster. Here is the error:

```
2023-03-23T13:47:39.786059Z ERROR agent::agentclient: error: Unable to operate on BottlerocketShadow: 'Unable to create the BottlerocketShadow associated with this node: 'Unable to create BottlerocketShadow (ip-10-250-82-160.us-east-2.compute.internal, 4be7304a-81c6-491d-b354-9eaac8ea3410): 'error sending request for url (https://brupop-apiserver.brupop-bottlerocket-aws.svc.cluster.local/bottlerocket-node-resource): error trying to connect: dns error: failed to lookup address information: Name does not resolve'''

```

Is there a setting I am missing that can make the domain configurable? Or is this something that will need to change to accommodate?
