Add support for Cloud Run v2 jobs
* create a separate file for service creation (service.tf) and job
(job.tf) - for easy comparison
* add E2E tests where possibile
* remove default value for input variable `region`
* fix subnet range VPC Access Connector example
* add creation of service account for audit logs call (trigger requires
service account)
* use provided trigger service account email in
`local.trigger_sa_email`, so explicitly provided SA is passed to
trigger
* set default value for vpc_connector_create.throughput.max, to match
what is set by GCP API, as provider uses wrong default of 300 which
results in perma-diff
* create inventory fiels for all examples
Global changes
* (tests) add input variable `project_number`, to allow assigning IAM permissions to Service Accounts in fixtures
* (tests) fix not outputting the path, when object is not found in inventory
* (tests) fix `create_e2e_sandbox.sh` - now it properly finds root of the repo
Secret Manager
* added `version_versions` output, to allow specifying versions in other modules. `versions` is sensitive and it makes it unsuitable for `for_each` values
New test fixtures
* `pubsub.tf` - creating one topic
* `secret-credential.tf` - creating Secret Manager `credential` secret
* `shared-vpc.tf` - creating two projects (host and service), and vpc in host project
* `vpc-connector.tf` - creating VPC Access Connector instance
