How to manage removing the first node pool but leave the second node pool in the array?

[prahaladramji]

eg. initial state.

node_pools = [
  {
    name         = "primary-node-pool"
    machine_type = "n1-standard-2"
  },
  {
    name         = "secondary-node-pool"
    machine_type = "n1-standard-2"
  },
]

later in the lifecycle, if we wanted to remove the primary-node-pool.

node_pools = [
  {
    name         = "secondary-node-pool"
    machine_type = "n1-standard-2"
  },
]

this basically tries to recreate a node and name it secondary-node-pool, this will fail cause that already exists.
