HDDS-2168. TestOzoneManagerDoubleBufferWithOMResponse sometimes fails…

… with out of memory error

After debugging this issue with @avijayanhwx and @bharatviswa504 , found out that mockito was the culprit here by consuming lots of heap memory to store the invocations.

Thanks to @avijayanhwx and @bharatviswa504 for helping!
