Allow local-exec to be skipped

[umairidris]

Some environments may not wish to have non-IaC scripts (run by provisioners like local-exec) being run in an automated way.

Where possible, these scripts should be skippable. For example:

• resource "null_resource" "wait_for_cluster".
• resource "null_resource" "delete_default_kube_dns_configmap"

I am happy to contribute. Would adding a new skip_provisioners bool (default to false) be an appropriate solution?

This is also an issue when running on Terraform Cloud where CLI utils gcloud and jq are not available on worker nodes. Currently, I'm unable to perform a successful apply due to the wait-for-cluster.sh script.

Yes, I think that can work. Thanks!
