Refactored Terraform code

[timclegg]

• Added DevRel defined tags (and ignored the default tags)
• Compatible with ORM, Cloud Shell and Terraform CLI
• Updated README to include instructions for all three methods
• Refactored, removing unnecessary resources (Vault, public Subnet, etc.).
• Added a nerd knob so that it could use an existing Group (rather than create a new one)
• Fixed ORM RegEx filters to allow dashes (-) and underscores (_), for the names
