Document configuration property
I have seen the code
if( "true".equals( System.getProperty( "PipelineExtensionDetector.expandFailures" )
but I couldn't see any documentation related to it. Can this be documented please?
The warning message that appears if that property is not set offers some documentation:
Failed to get some classes of type [{}] in package [{}]. For detailed error messages, set the system property PipelineExtensionDetector.expandFailures=true. Failures: [{}]https://github.com/ExpediaGroup/jenkins-spock/blob/master/src/main/java/com/homeaway/devtools/jenkins/testing/WholeClasspathPipelineExtensionDetector.java#L79-L83
In practice, the message might look like this:
[2020-03-16 12:25:28,052](main)([]) WARN WholeClasspathPipelineExtensionDetector - Failed to get some classes annotated with [interface hudson.Extension] of type [class org.jenkinsci.plugins.workflow.steps.StepDescriptor] in package [Optional.empty].

If there are no failures, then this property will have no effect. If there are failures, the message that they generate instructs people in the property's usage.
We could add a mention of it in documentation proper.
