Commit Message

Aggressively free test memory

In some runs an out-of-memory error would occur locally due to a higher
concurrency than the CI resulting in more GC pressure. At 512mb heap it
could fail, despite test methods being friendly to collect. The memory
grabs are more aggressively cleared, helping to cut the heap in half
when inspecting the heap dumps.

1. Set the Awaitility executor to avoid finalization
(awaitility/awaitility#168)
2. Use same-thread poll in verifier to avoid async pile up due to
lambda not being GC'd promptly
3. Assist GC by removing circular references in timer wheel sentinel
4. Assist GC by clearing the cache's data and null'ing node links
5. Remove heavy-weight testng context
6. Enable parallel ref cleanup to better discard weak/soft entries
