ephemeral resource: Add kubernetes_secret and kubernetes_secret_v1 support

[shivasheesh-yadav]

Description

We fetch kubernetes secrets in terraform using data source, but they end up getting stored in terraform state file.
We would like to use the new feature "ephemeral resources" so that kubernetes secrets aren't stored in terraform state.

Potential Terraform Configuration

ephemeral "kubernetes_secret" "test_secret" {
  metadata {
    name      = "test-secret"
    namespace = "test-namespace"
  }
}

locals {
  test_secret_data = ephemeral.kubernetes_secret.test_secret.data["password"]
}
