This PR update to Go 1.18.2. Also update the versions of hclfmt
and go-hclogfmt which includes newer dependencies necessary for dealing
with go1.18.
The hcl v2 branch is now 'nomad-v2.9.1+tweaks2', to include a fix for
newer macOS versions: 8927e75e82
Also format terraform scripts with hclfmt, equivalent to terraform fmt.
I opted not to use terraform fmt, because I didn't want to introduce dev dependency on the terraform CLI.
Also, I've optimized the find command to ignore spurious directories (e.g. .git, node_modules) that seem to be populated with too many files! make hclfmt takes 0.3s on my mac down from 7 seconds!
This module is based on the current AWS and Azure configurations, with a few tiny GCP-specific modifications:
* Defaults to only allow your Terraform's host external IP address, which can be optionally disabled. Otherwise, the UIs/APIs are exposed on the internet.
* Exposes the Vault UI and API through the load balancer.
* Uses GCP oslogin to facilitate VM SSH access, without an external SSH IP for all instances.
* Provides optional way to enable preemptible VM instances to save money.
