DynamoDB autoscaling

Note: upgrade from v1.x to v2.x

Starting from v2.0.0 of this module, the name of Vault's DynamoDB table will be dynamically generated from the values of "${var.project}" and "${var.environment}". In previous versions it was hardcoded to vault-dynamodb-backend, so to avoid breaking current deployments, we've introduced a new variable dynamodb_table_name_override to force a specific name for the DynamoDB table. So if you're upgrading from a previous version of the module, you'll probably want to set dynamodb_table_name_override=vault-dynamodb-backend so Terraform doesn't recreate the table.

Initial release

Corresponds to release 2.3.3 of the terraform-instances repo (old location of the vault module)
