Trying to provision a simple workspace.  All the code I can find look something like the following, where credential/storage/network resources are created, then referenced. 

In my case, it's a separate repo and try to reuse existing configurations.  I was able to query mws_credential and find credential_id, but there are no data source for storage_configuration and mws_networks, according to databricks documentation.

Any hints where I should look?  Undocumented data sources?  Wrapped up somewhere in other sources?  I can see both configuration_id and network_id in tfstate but that's probably a bit too much

Thanks

data "databricks_mws_credentials" "all" {
  provider = databricks.mws
}

resource "databricks_mws_workspaces" "this" {
  provider                 = databricks.mws
  credentials_id           = databricks_mws_credentials.this.credentials_id
  storage_configuration_id = databricks_mws_storage_configurations.this.storage_configuration_id
  network_id               = databricks_mws_networks.this.network_id
  ... ...
}

resource "databricks_mws_credentials" "this" {
  provider         = databricks.mws
  ... ...
}

resource "databricks_mws_storage_configurations" "this" {
  provider                   = databricks.mws
  ... ...
}

resource "databricks_mws_networks" "this" {
  provider           = databricks.mws
  security_group_ids = var.security_group_ids
  subnet_ids         = var.vpc_private_subnets
  vpc_id             = var.vpc_id
  ... ...
