Support retentionTimeout and waitForPodSec

[AhmadMasry]

What does this PR do?

Add the ability to modify retentionTimeout and waitForPodSec default value in JCasC:

• retentionTimeout: For tasks that use very large images, this timeout can be increased to avoid early termination of the task while the Kubernetes pod is still deploying.
• waitForPodSec: This will change how long Jenkins will wait (seconds) for pod to be in running state.

Is there anything I can do to fix the tests or to go forward?

You need to update the checksums, the new ones are in the logs, search the string that is failing in the test and replace it with the new one
