Support using along terraform-google-provider 4.x.x

[jackwhelpton]

TL;DR

Need to be able to use the Google provider v4, required by upstream modules.

Expected behavior

Module is usable with Google provider 4.0.

Observed behavior

Could not retrieve the list of available versions for provider hashicorp/google: no available releases match the
│ given constraints >= 2.12.0, >= 3.43.0, >= 3.45.0, ~> 3.53, >= 4.0.0, < 4.0.0, < 5.0.0

Additional information

The terraform-google-vm module has already been updated: that is one of the dependencies that currently pins the version here. Until that's released, I'll use the master branch from that repo to unblock myself while fixing everything else.

PR (work in progress): #98. This seems to pass all checks, but will need a further update once the changes to terraform-google-vm have been released, and shouldn't be merged until then.
