GCE: backendServices and healthChecks not managed by KOPS are being Deleted

[VitusAcabado]

/kind bug

1. What kops version are you running? The command kops version, will display
this information.
1.30.1

2. What Kubernetes version are you running? kubectl version will print the
version if a cluster is running or provide the Kubernetes version specified as
a kops flag.
v1.30.6

3. What cloud provider are you using?
GCE

4. What commands did you run? What is the simplest way to reproduce this issue?
kops delete cluster --yes

5. What happened after the commands executed?
Kops tries to delete backend services/healthchecks it does not manage. These resources were created via our IAC, and kops delete fails because they are attached to another load balancer not associated with kops.

6. What did you expect to happen?

7. Please provide your cluster manifest. Execute
kops get --name my.example.com -o yaml to display your cluster manifest.
You may want to remove your cluster name and other sensitive information.

8. Please run the commands with most verbose logging by adding the -v 10 flag.
Paste the logs into this report, or in a gist and provide the gist link here.

9. Anything else do we need to know?

This happens if there are no backends attached to a Backend Service
This function returns true as it never goes into the for loop, causing the kops client to add a delete resource task.
