      Cause: Users may desire to configure their AWS DHCP Option Set with a custom domain name, that contains a trailing period.
      Consequence: The current logic for extracting the hostname of EC2 instances and turning that into Kubelet node names does not trim the hostnames for trailing periods. A trailing period is not permitted in a Kubernetes object name per the DNS 1123 subdomain name standard.
      Fix: The logic has been updated to trim trailing periods should they exist.
      Result: Trailing periods are now permitted within the domain name in the DHCP Option Set.
