- add support to provision VMs on googlecloud
- refactor the way we define the project used by Terraform
(we'll now use the GOOGLE_PROJECT environment variable,
and if it's not set, we'll set it automatically by getting
the default project from the gcloud CLI)
Break down provider-specific configuration into two files:
- config.tf (actual configuration, e.g. credentials, that cannot be
included in submodules)
- variables.tf (per-provider knobs and settings, e.g. mapping logical
VM size like S/M/L to actual cloud SKUs)
