[ISSUE] The databricks_group_member resource shouldn't allow you to add users to the "users" group

[Xophmeister]

Configuration

data "databricks_group" "users" {
  display_name = "users"
}

resource "databricks_user" "test" {
  user_name    = "[email protected]"
  display_name = "Testy McTestface"
}

resource "databricks_group_member" "membership" {
  group_id  = data.databricks.users.id
  member_id = databricks_user.test.id
}

Expected Behavior

The users group is a pseudogroup of all users in Databricks, which you should never explicitly add users to. The provider should forbid this.

Actual Behavior

This works fine. The problem comes when you try to destroy the membership resource: The Databricks API forbids this and so terraform destroy will fail.

Steps to Reproduce

1. terraform apply
2. terraform destroy

Terraform and provider versions

Terraform v1.0.11
on linux_amd64
+ provider registry.terraform.io/databrickslabs/databricks v0.4.7

databricks_group_member knows nothing of system groups - it operates purely on IDs.
