Add MachineOptionsWithName configuration option
What does this MR do?
Allow machine options to reference the machine name by providing a template field that supports %s placeholders for dynamic machine-specific configuration
Why was this MR needed?
This will allow us to add the machine name as a label via this configuration:
MachineOptionsWithName:
- google-label=runner-manager-instance-name:%s
Which will then allow fine-grained attribution via billing data.
What's the best way to test this MR?
I will test it locally.
