Terraform DigitalOcean module for Instellar

This module automatically forms LXD cluster on DigitalOcean. This terraform module will do the following:

• Setup networking
• Setup bastion node
• Setup compute instances
• Setup Private Key access
• Automatically form a cluster
• Destroy a cluster
• Enable removal of specific nodes gracefully
• Protect against database-leader deletion

These functionality come together to enable the user to fully manage LXD cluster using IaC (infrastructure as code)
