Sets `AWS_SDK_UA_APP_ID` in the Terraform provisioner environment so
that all AWS API calls made during workspace builds include Coder's AWS
Partner Revenue Measurement (PRM) attribution in the user-agent header.
This enables AWS to attribute resource usage driven by Coder back to us
as an AWS partner across all deployments.
## How it works
- `provisionEnv()` now unconditionally sets
`AWS_SDK_UA_APP_ID=APN_1.1/pc_cdfmjwn8i6u8l9fwz8h82e4w3$` in the
environment passed to `terraform plan` and `terraform apply`
- The Terraform AWS provider picks this up and appends it to the
user-agent header on every AWS API call
- If a customer has already set `AWS_SDK_UA_APP_ID` in their environment
(e.g. via `coder.env`), we don't override it
- Templates that don't use the AWS provider are unaffected — the env var
is simply ignored
## Notes
- The product code is hardcoded in the source. It may be worth
obfuscating this value (e.g. via `-ldflags -X` at build time) to keep it
out of the public repo, though it is technically a public identifier.
- This covers user-agent attribution only. Resource-level `aws-apn-id`
tags for cost allocation are a separate effort that requires template
changes.
