@sheneska , could you please update the mmv1/provider/terraform/common~copy.yaml file to insert this block of code:

<%
  Dir["third_party/terraform/META.d/*.yaml"].each do |file_path|
    fname = file_path.delete_prefix("third_party/terraform/")
-%>
'<%= fname -%>': '<%= file_path -%>'
<% end -%>

directly above this section at the end of the file:

magic-modules/mmv1/provider/terraform/common~copy.yaml

Lines 140 to 143 in f26f4e7

	'.teamcity/.gitignore': 'third_party/terraform/.teamcity/.gitignore'
	'.teamcity/Makefile': 'third_party/terraform/.teamcity/Makefile'
	'version/version.go': 'third_party/terraform/version/version.go'
	'go.sum': 'third_party/terraform/go.sum'

---

That file instructs the code generator how to copy static files into the downstream google and google-beta repos. The new block makes the generator find all YAML files in the META.d folder and copies them into a META.d folder in the provider repos.

Edit: without this change, your PR results in no changes to the downstream providers as the files aren't being copied over yet

@sheneska I was about to merge but then figured I'd ask - should the files be different for the google and google-beta providers? If you click the links in this report you can see how this PR changes those providers by adding files with the same content.

If the files being the same in the google and google-beta provider repos is OK, we can get this PR merged 🚀

[SarahFrench]

After conversations on Slack we've agreed that having the same info passed into the TPG/TPGB repos is ok. Merging now.
