Refactor MemoryLeakTestSuite

Browse Source 
as we identified two issues where the goroutine count from before differs from after the test.

1) It seemed like a Go runtime specific Goroutine appeared in rare cases before the test. To avoid this, we introduced a short timeout before looking up the Goroutines.
Another solution might be to do the lookup twice and check if the count matches.

2) A Goroutine that periodically monitors some storage unexpectedly got closed in rare cases. As we could not identify the cause for this, we removed the leaking Goroutines by properly cleaning up.
