cluster-id with just VC-IP on multi clustered VC is error prone

[rpanduranga]

Issue/Feature Description:
cluster-id with just VC-IP on multi clustered VC is error prone

cluster-id: The unique cluster identifier. Each Kubernetes cluster must contain a unique cluster-id set in the configuration file. The cluster ID cannot not exceed 64 characters.

What type of Issue/Feature is this?

Uncomment only one /kind <> line, hit enter to put that in a new line, and remove leading whitespace from that line:

/kind bug fix

Why this fix/ feature is needed(give scenarios or use cases):
Currently the vsphere-config-secret is created with the cluster-id as VC-IP
here is the decoded output of the secret

[Global]
cluster-id = "VCIP"

[VirtualCenter "VCIP"]
insecure-flag = "true"
user = "[email protected]"
password = "Admin!23"
datacenters = "VSAN-DC"

On the multi clustered VC, if the two or more clusters are configured with the same cluster-id then it is an error prone for the
CNS analytics

How to reproduce, in case of a bug:
Configure a setup with multi cluster and deploy multiple k8s cluster in it
