      Description

      An extension of HBASE-10263 per Ted Yu's suggestion.

      brief description of this extension is as below:
      1. if the global inMemoryForceMode is on, all in-memory blocks are preemptive no matter what their per-column-family inMemoryForceMode are;
      2. if the global inMemoryForceMode is off, only in-memory blocks of column-family with inMemoryForceMode on are preemptive; non-preemptive inMemory blocks respect the single/multi/memory ratio;

      In short, global flag dominates, and per-column-family flag can only control its own blocks.
