feat: add terraform to bundle deploy

[marcoppenheimer]

Changes Made

feat: add ability to use terraform

• Updates .gitignore to not track state files
• Updates README.md to include install + deploy instructions
• Adds terraform/* for dev/prod deployments:
  • Symlinks to root directory as per TF best practices
  • Uesr configuration managed in <env>.auto.tfvars
  • Default configuration managed in vars.tf
  • Specifies machine constraints, which currently the Juju bundle equivalent does not have
  • Is unable to set storage constraints (I think), which currently the Juju bundle equivalent does have
  • Deploys a data-integrator by default
• Added a terraform fmt to tox -e fmt. Nicer style

Looks very good! Just before merging, could we maybe just put this deployment into a small integration tests where we just do

terraform apply

and make sure that everything comes up? A bit like what we do for bundles as well?
