Fixes netty byte buffer releases in edge case scenarios:

- Ensure async select server uses a callback if the cluster had been closed
- Ensure that handleReadResponse checks to see if the cluster had been closed
  before retaining incoming buffers
- Ensure closing the netty stream releases all references

Test fixes
- Ensure tests run using paranoid leak detection
- Fail the testsuite if a leak is detected.
- Fixed releasing buffers in the ByteBufferBsonOutputTest.
