We were not waiting on for informers to fully shutdown for level-driven controllers. As a consequence, goroutines would still be running handling events while the next unit test case ran. In this case, a handler with no workqueue (like node_tracker) would attempt to read global config, while the next test case was modifying the global config, leading to a data race.
Fixes: #4381
Thanks to @npinaeva for helping me debug this one!
