Update Hazelcast version, remove security vulnerability

Security vulnerabillitles were flagged in CLM in Hazelcast
version 3.11-BETA-1. Hazelcast version 4.1.1 removes that vulnerability.
The lock handling is slightly different in version 4.1.1 and the old
ILock class is removed. The code is updated to use the new FencedLock
locks.
