Use .terraform/terraform.tfstate when local state is unavailable

[cbarbour]

Description

Feature request.

Currently, terraform inventory checks the current working directory for the terraform.tfstate file. When configured to use a remote state, terraform places the state file in the .terraform/ directory instead.

It would be useful for terraform-inventory to check for .terraform/terraform.tfstate if it doesn't find the state in the root of the terraform configuration. This would make life simpler for folks using remote state, and might help avoid the need to wrap terraform-inventory to pull state from a s3 bucket or other remote location.

Steps to reproduce

1. Create a S3 bucket for remote state
2. Configure Terraform to use remote state
3. Confirm that the state was successfully pushed, and that a copy exists in .terraform
4. Remove the local state files.

Configuration example

terraform remote config -backend=s3 \
  -backend-config="bucket=myproject-terraform-state" \
  -backend-config="key=myproject/terraform.tfstate" \
  -backend-config="region=us-east-1"

Versions

• terraform-inventory version '0.6.1'
• Terraform v0.7.0

Additional information

Remote state include a remote block to preserve the remote configuration. This seems to cause no issues for terraform-inventory. I can confirm that terraform-inventory reads the file just fine.

Thanks for the detailed feature request. This is a fantastic idea, which I've taken a stab at in #41. Would you mind taking a look and letting me know if it works for you?
