Remove any VMs as part of the offboarding process

Closed username-removed-897310 requested to merge remove_terraform_files into master

When a team member leaves the company we need to make sure there aren't any development VMs left behind.

This MR ensures the removal is part of the offboarding process and isn't left behind. It is enough to delete the Terraform file: the CI will take care of it as soon as the MR is merged into master.
