fix: Use variable to enable EKS cluster creation with CONFIG_MAP authentication mode

[hsalluri259]

Description

Using enable_cluster_creator_admin_permissions variable for bootstrap_cluster_creator_admin_permissions in place of hard coded false value to support EKS cluster creation when authentication mode is CONFIG_MAP only. I think alternatively we can use API_AND_CONFIG_MAP, but this will take time for us to migrate our clusters and customers clusters.

Motivation and Context

It allows a user to create an EKS cluster when authentication mode is CONFIG_MAP only by using bootstrap_cluster_creator_admin_permissions=true .
Without this value, the user will be facing the below error.

Error: creating EKS Cluster (k8s-dev-eks-xyz: operation error EKS: CreateCluster, https response error StatusCode: 400, RequestID: eec24135-0159-484f-b0d7-b5c5518b3cd5, InvalidParameterException: bootstrapClusterCreatorAdminPermissions must be true if cluster authentication mode is set to CONFIG_MAP

It fixes the following open issue.
#3247

Breaking Changes

The default value for bootstrap_cluster_creator_admin_permissions variable is still false. So it doesn't break anything.
