--with-terraform
Installs Terraform binary from https://releases.hashicorp.com/terraform/${TERRAFORM_VERSION}/ source
alongside coder.
This is great for if you are having issues with Coder installing terraform, or if you
just want it on your base system aswell.
This supports most systems, however if you are unsure yours is supported you can check
the link above.


The detection method works as follows:
- Debian, Ubuntu, Raspbian: install the deb package from GitHub.
- Fedora, CentOS, RHEL, openSUSE: install the rpm package from GitHub.
