Add deployment field to agent dispatch in TokenSource

Add support for targeting specific agent deployments when using TokenSource:
- Add AgentDeployment property to TokenSourceFetchOptions
- Add Deployment field to AgentDispatch class
- Include deployment in BuildRequest when any agent field is set

Leave deployment empty to target the production deployment.
