IAP has no reasonable support policy, because PATCH is broken, and IAP
must be configured with an OAuth2 client ID and secret that belongs to
the project the app is associated with. There's no programmatic way to
create Clients. But we create the project and the app at the same time,
and we can't update because PATCH is broken. So this just drops IAP. It
also forces all our updates to ForceNew, because we can't update.
Also, adds more test coverage and docs, and fixes import by not relying
on the config for setting app engine info in state.
+ Make the org_id optional when creating a project. Closes#131
+ Mark org_id as computed to allow for GCP automatically assigning the org.
+ Add an acceptance test for project creation without an organization.
+ Skip TestAccGoogleProject_createWithoutOrg if GOOGLE_ORG is set.
+ Add a folder_id to the google_project resource, optionally
specifying the ID of the GCP folder in which the GCP project should
live.
+ Document how one can provision a project into a folder, and added a
sample configuration to create a project into an existing folder.
* Skip test without org if service account is used
* Support folders/* or id only for the folder id field
