[feature] Support for Terraform 0.13

[arnaudlh]

Proposal

Add support for Terraform 0.13 in two waves:

1. Compatible: able to run on Terraform 13. possibly on Terraform 12.
2. Optimized: leverage Terraform 13: for landing zones leverage features as count for_each depends_on.

Landing zones

• landingzone_vdc_demo
• landingzone_hub_spoke
• landingzone_caf_foundations
• landingzone_secure_vnet_dmz
• landingzone_hub_mesh

Dependencies

• Provider azurecaf present in the registry

When trying to instantiate landingzone_caf_foundations on 0.13beta2 via TFE or the local binary, I'm observing issues where its trying to find the azurecaf provider within aztfmod (this is signed and successful) as well as the hashicorp namespace (this is not for obvious reasons). Since it fails to find azurecaf in the hashicorp namespace the plan fails. This doesn't happen unless I start taking advantage of the blueprint/modules - just setting the required provider and using an azurecaf resource works fine. I can't seem to locate where the problem might be. At first I assumed we just had an azurecaf provider called out in a module/submodule without the aztfmod namespace being defined but I can't find it. I even removed version pinning to see if I was leveraged an out of date module. Obviously 0.13 is beta, and this is still work in progress - but it seemed worth calling out the issue here since it seemed to be working for TFC in the demo on youtube.

Hi @frodopackets, we use the provider from the registry, available here
and you should call it using:

terraform {
  required_providers {
    azurecaf = {
      source = "aztfmod/azurecaf"
    }
  }
}

The hashicorp/azurecaf error message you are referring to - is due to modules trying to locate the provider "the old way".

Updated modules are now in test and you can check the code I'm using for the demo here: https://github.com/arnaudlh/caf-terraform-landingzones-tfc/tree/master/landingzones/landingzone_caf_foundations

HTH.

Working branch for this one is vnext13 - https://github.com/Azure/caf-terraform-landingzones/tree/vnext13

since GA of Terraform 0.13 has been pushed to 10th August as per hashicorp/terraform#25016
we will align and release 13 capabilities in 2008 (august release). in the meantime you can still use the vnext13 branch (https://github.com/Azure/caf-terraform-landingzones/tree/vnext13) to follow the updates
