Problem Description

Although unlikely, if a user tries to start a trained model deployment with a ridiculously large queue_capacity (for example 9999999999999, the node that tries to allocate the model will immediately crash.

Furthermore, the node will continue to crash when restarted, as soon as the node attempts to allocate the trained model deployment.

Steps to Reproduce

1. Import a trained model
2. Start the trained model deployment with queue_capacity=9999999999999
3. Notice that the ML node that attempted to start the trained model deployment has crashed
4. Try restarting the node
5. Notice that the node continues the crash as soon as it tries to allocate the trained model deployment

Logs (if relevant)

The Elasticsearch instance crashes immediately after logging the attempt to start the trained model deployment. No logs after that.
