Upgraded to Hazelcast 3.2 

Signed-off-by: richardhightower <richard.m.hightower@gmail.com>

This is to upgrade to Hazelcast 3.2.

All of the tests were run.
97% of all tests passed.
The 3% that failed were the same three percent that were failing on OSX before the change was applied.

The bug report is here. I have signed the Eclipse contributor agreement.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=432697


No tests relating to clustering or hazelcast failed, and the tests that failed were failing before changes.
