Provisioned GKE cluster NUM_NODES is not matching the nodeCount spec

[ytsarev]

What happened?

Encountered via higher level upbound/platform-ref-gcp#91 platform ref testing

I was debugging the issue with clean deletion and noticed that NUM_NODES of provisioned GKE is not matching the spec

$ gcloud container clusters list --region=us-west2 --project=official-provider-testing
NAME                          LOCATION  MASTER_VERSION      MASTER_IP     MACHINE_TYPE  NODE_VERSION        NUM_NODES  STATUS
platform-ref-gcp-bngsf-6wqpt  us-west2  1.29.1-gke.1589018  34.94.11.113  e2-medium     1.29.1-gke.1589018  3          PROVISIONING

$ gcloud container clusters list --region=us-west2 --project=official-provider-testing
NAME                          LOCATION  MASTER_VERSION      MASTER_IP     MACHINE_TYPE  NODE_VERSION        NUM_NODES  STATUS
platform-ref-gcp-bngsf-6wqpt  us-west2  1.29.1-gke.1589018  34.94.11.113  e2-medium     1.29.1-gke.1589018  6          RUNNING

In addition, it also dynamically growing, apparently by some condition on the cloud provider side.

MACHINE_TYPE is also something to double check

How can we reproduce it?

Provision this configuration or platform-ref-gcp, run gcloud commands above

What environment did it happen in?
