support MemorySafeLinkedBlockingQueue

Hello community:


Since PR[1] get merged, I found a better way to limit the memory used by `BlockingQueue`.


This `MemorySafeLinkedBlockingQueue` uses `MemoryLimitCalculator` to solve the memory problem:  when the available memory of the JVM is less than a certain value, the queue no longer `offer`.




I submit a PR[2], you can see ISSUE[3] to get more details.


If you are free, please see the PR[2] and help this PR[2] to solve the problem better.

Looking forward to your reply.
