At present, Hazelcast configurations used in tests disable multicast join but leave network join auto-detection enabled. This can cause issues with parallel test execution on machines that have bigger number of CPU cores/threads.
This commit updates Hazelcast configurations used in tests to disable network join auto-detection and thus ensure no network join method ends up being enabled.
Before making these changes, a number of Hazelcast tests regularly fail on my desktop (Ryzen 5 5600X with 6 cores/12 threads).
Update:
I would hold off merging this for now because I plan to also try and see if other supported branches are affected by the same issue.
