Add a configuration to disable the slab cache by default
--------------------------------------------------------

                 Key: HBASE-5267
                 URL: https://issues.apache.org/jira/browse/HBASE-5267
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.92.0
            Reporter: Jean-Daniel Cryans
            Assignee: Li Pi
            Priority: Blocker
             Fix For: 0.94.0, 0.92.1


>From what I commented at the tail of HBASE-4027:

{quote}
I changed the release note, the patch doesn't have a "hbase.offheapcachesize" configuration
and it's enabled as soon as you set -XX:MaxDirectMemorySize (which is actually a big problem
when you consider this: http://hbase.apache.org/book.html#trouble.client.oome.directmemory.leak).

We need to add hbase.offheapcachesize and set it to false by default.

Marking as a blocker for 0.92.1 and assigning to Li Pi at Todd's request.
