Not compatible with Terraform v0.12 and the new state pattern

[pitthecat]

Hi there,

the Terraform v0.12 update broke terraform-inventory. It can no longer read or interprete the new state file pattern.

Error Message:
Usage: terraform-inventory [options] path
path: this is either a path to a state file or a folder from which terraform commands are valid

With best regards

I'm probably not going to get to this any time soon, because I'm busy with other things. Pull requests to fix this would be greatly appreciated. Per the changelog it looks like we ought to be running terraform show -json to fetch the state in JSON format now, rather than reading the file directly.

I'm currently actively working on this since yesterday afternoon, using @adammck's above suggestion of using terraform show -json and trying to stay compatible with both versions (thanks to unit tests 👍).

Fixed in #114 - check out that branch and try it - works for me.

Fixed by #114.
