[2byrds]

Use the EBA load test data to test and publish limits of a single vlei-verifier instance, configured for the EBA scenario.
It should include information such as:

• How many test vlei chained credentials can it process per minute
• How many production vlei chained credentials can it process per minute
• Any configuration information that impacts performance
• Recommendations for improving the throughput
• Recommendations for scaling the vlei-verifier service.
