Remove dependencies on terraform-aws-account-metadata. Use Terraform vars.

[aknysh]

what

• Remove dependencies on terraform-aws-account-metadata
• Use Terraform vars instead (which could be be provided from Dockerfile or chamber)

why

• Maketerraform-root-modules a generic Terraform module that could be used for different projects (including third-party) and for Cloud Posse documentation
• terraform-aws-account-metadata is a private repo and contains secrets
• Eliminate cold-start cycles
• Fewer repos to maintain

I think this is a good change.
