Allow import of GCP projects

[ensslen]

GCP project names can not be reused, attempting to do so results in a 409 error. However, this module won't accept an imported project, e.g. terraform import module.X.google_project.main my-project, because id and project_id can not be supplied as inputs. The imported project results in

-/+ module.my-project.google_project.main (new resource required)
id: "my-project-name" => (forces new resource)
auto_create_network: "true" => "false"
billing_account: "XXXXX-XXXXX-XXXXX" => "XXXXX-XXXXX-XXXXX"
folder_id: "" =>
name: "my-project-name" => "my-project-name"
number: "808999117972" =>
org_id: "1234567890" => "1234567890"
policy_data: "" =>
policy_etag: "" =>
project_id: "my-project-name" => "${local.temp_project_id}" (forces new resource)
skip_delete: "" =>

Hi @ensslen. Thank you for your interest in the project! I apologize for the extreme delay in responding.

Since project-factory v2.1, project_id is an optional variable, but that only solves part of this problem as the ultimate value passed to the google_project has sufficient interpolation complexity to cause an imported project to be recreated even when its ID is provided as an input. We are investigating moving the complexity around the project ID calculation out of the core-project-factory submodule which should allow you to invoke that submodule directly with an imported project.

Can I fill in a existing project name without fear of losing the name? I fear it will be deleted and then won't be able to use that name anymore.

@nicobrinkkemper support is not in place for importing existing projects.

Any idea on when an import feature may be added? I ran into an issue while using non-random project names where the project was created, but the state file was not updated (caused by network issues). This resulted in me not being able to use the project name any more, and is causing much pain for my customers. I undeleted the project, but can't get it into the state file, and is making using terraform a real obstacle at this point. Thanks!

@cochrasc What happens if you attempt to import using terraform import?

[aaron-lane]

We should ensure that at least the core_project_factory submodule can be used with an imported project. If the root module, shared_vpc submodule, and gsuite_enabled submodules can be used with an imported project, that will be a bonus.

@aaron-lane I've tested imports with main module, core_project_factory and shared_vpc submodules. Works fine.
