* [terraform/aws] Fix Terraform >=0.13 warnings Terraform >=0.13 gives the following warning: ``` Warning: Interpolation-only expressions are deprecated ``` The fix was tested as follows: ``` rm -rf .terraform && terraform0.12.26 init && terraform0.12.26 validate rm -rf .terraform && terraform0.13.5 init && terraform0.13.5 validate rm -rf .terraform && terraform0.14.3 init && terraform0.14.3 validate ``` which gave no errors nor warnings. * [terraform/openstack] Fixes for Terraform >=0.13 Terraform >=0.13 gives the following error: ``` Error: Failed to install providers Could not find required providers, but found possible alternatives: hashicorp/openstack -> terraform-provider-openstack/openstack ``` This patch fixes these errors. This fix was tested as follows: ``` rm -rf .terraform && terraform0.12.26 init && terraform0.12.26 validate rm -rf .terraform && terraform0.13.5 init && terraform0.13.5 validate rm -rf .terraform && terraform0.14.3 init && terraform0.14.3 validate ``` which gave no errors nor warnings for Terraform 0.13.5 and Terraform 0.14.3. Unfortunately, 0.12.x gives a harmless warning, but with 0.14.3 out the door, I guess we need to move on. * [terraform/packet] Fixes for Terraform >=0.13 This fix was tested as follows: ``` export PACKET_AUTH_TOKEN=blah-blah rm -rf .terraform && terraform0.12.26 init && terraform0.12.26 validate rm -rf .terraform && terraform0.13.5 init && terraform0.13.5 validate rm -rf .terraform && terraform0.14.3 init && terraform0.14.3 validate ``` Errors are gone, but warnings still remain. It is impossible to please all three versions of Terraform. * Add tests for Terraform >=0.13
