Folder support: Assign/Reassign a google project to a folder. (#438)

+ 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
