[Story] Scorecard tests with Cryostat Agent

We should have scorecard tests that use the Cryostat Agent instead of remote JMX. This would involve:
1. Adding a CI job, possibly to the Cryostat Agent repo, that builds a sample application container image with the appropriate Cryostat agent jar included with it.
2. Write a Scorecard test that deploys and configures the sample application to successfully register with Cryostat and perform the recording actions in the existing `cryostat-recording` test.

Locate the existing `cryostat-recording` Scorecard test and the repository's CI entry points; first trace how that test deploys and configures the sample application and currently uses remote JMX. Add coverage using a sample image containing the Cryostat Agent, and verify that registration and recording actions succeed in CI.
