Jtrunner fails if interview jtb includes answers not in expected interview

Jtrunner fails if interview jtb includes answers not in expected interview.
This is typically seen when doing a customruntime for and individual/few testcases, whereby the Harness determines from the small set of tests the required interview questions. However currently Jtrunner generates a JTB response file based on the top-level group, which can include more answers than is required for the tests selected. This causes the error like:

Configuration file can not be imported due to question with specified tag "jck.env.runtime.xxxxx" was not found on path. The path is:jck.intro .....

A solution to this is to change the Jtrunner so it generates only a top-level answer JTB, ie. the very basic info that is valid for all tests, then for other properties that are only valid for some tests within a group, to instead update the runtime.jti Java property file with those values, ie.:

1. Download jck/jtrunner/config/jck21/runtime.jti into a temp name, eg.runtime_temp.jti
2. Determine required properties for test group, and set property values in runtime_temp.jti
3. Run Harness using @GenericTopLevel.jtb @runtime_temp.jti
