Refactor main.tf and add infra mix tasks

Refactor main.tf to use the correct project name (oops).

Add terraform infra(structure) tasks to projects mix file:
  - infra.apply: Deploys the infra. according using terraform
  - infra.destroy: Destroys the currently deployed infrastructure
  - infra.plan: Plans a deployment using terraform
