Enhance oci_core_route_table_attachment to support assiging route table to a VLAN

[olkoko]

Description

Attempting to create a VLAN with a route table that has a route rule to a private IP in that VLAN.
Getting a cycle error when attempting to do so.

│ Error: Cycle: oci_core_private_ip.this, oci_core_route_table.this, oci_core_vlan.this

Seems like you should be able to create a VLAN, private IP in this VLAN, route table with a rule refering private IP, and then associate route table with VLAN.

This can be achieved by enhancing oci_core_route_table_attachment to support attaching route table to a VLAN.

New or Affected Resource(s)

• oci_core_vlan
• oci_core_private_ip
• oci_core_route_table
• oci_core_route_table_attachment

Potential Terraform Configuration

resource "oci_core_route_table_attachment" "this" {
  vlan_id = var.vlan_id
  route_table_id = var.route_table_id
}
