v1.0.0

Added

• Support for multi-region, multi-zone deployments in GCP.
• Support for multi-zone deployments in AWS. Since multi-region deployments require
  separate provider blocks, we don't allow multiple regions to avoid increased repo complexity.
• Support for GPUs on GCP (via the terraform accelerator block) and AWS. Includes driver installation script
  and a gpu-specific docker-compose.yaml file to expose GPUs to the node container for diagnostics.
• Terraform formatter in pipeline and README.

Changed

• Format of node specification in .tfvars. Nodes are now specified via a map (see variables.tf) where keys correspond to node IDs.
• Format of router specification in .tfvars. Router is now specified via a map (see variables.tf).
• Naming conventions for configuration .json files. One file per deployed node, names (without .json postfix) matching the node IDs (keys of nodes from variables.tf), are now the only requirements.

Fixed

• All created resources are now parametrized by cluster name, so no conflicts arise from successive deployments within the same project.
