* ci: Update DataDog GitHub branch to fallback to GITHUB_REF
This was detecting branches, but not our "main" branch before.
Hopefully this fixes it!
* Add basic Terraform Provider
* Rename post files to upload
* Add tests for resources
* Skip instance identity test
* Add tests for ensuring agent get's passed through properly
* Fix linting errors
* Add echo path
* Fix agent authentication
* fix: Convert all jobs to use a common resource and agent type
This enables a consistent API for project import and provisioned resources.
* feat: Add agent authentication based on instance ID
Each cloud has it's own unique instance identity signatures, which
can be used for zero-token authentication. This change adds support
for tracking by "instance_id", and automatically authenticating
with Google Cloud.
* Add test for CLI
* Fix workspace agent request name
* Fix race with adding to wait group
* Fix name of instance identity token
