v0.10.0

MAJOR CHANGE: Terragrunt now expects its configuration to be defined in a terraform.tfvars file instead of a .terragrunt file. Check out the README for what the terraform.tfvars file should look like and the migration instructions for how to move to the new format (it's VERY easy!). For backwards compatibility, the .terragrunt format WILL continue to work, but it is now deprecated.

The main reasons for this change are:

1. Instead of introducing a new file format into your Terraform projects, Terragrunt now piggybacks on top of the .tfvars format Terraform already uses for defining variables.
2. We reduce the number of files you need. This is especially valuable with remote Terraform configurations, as it means you only need a single terraform.tfvars file to define what code to download and provide the variables for that code.
