create global variables in beforeSuite Action

[Feature Request]

As a Backend Tester I would need the capability to save a session/topic/channel identifier received during the beforeSuite action from a SUT into the global variables. These Identifiers are needed to access application resources behind a interface (HTTP, Websocket) in each testcase. Additionally this identifier is also needed in afterSuite to tear down the logical connection.

Without this feature I would need to bring up and tear down logical connections in each testcase.

Start by locating the beforeSuite and afterSuite lifecycle actions and the global-variable handling used by the test framework. Trace how a session, topic, or channel identifier from the SUT could be retained for testcases and teardown, then verify the behavior across the HTTP and WebSocket interfaces mentioned in the request.
