update hazelcast to 3.9 and add hz-list to retrieve a list from hazelcast

[tolitius]

thanks for PR. A couple of comments:

• pom {:project 'hellonico/chazel'..} here is probably a commit mistake

• why to 3.9 and not to 3.9.2?

I did update chazel to 3.9.2 before, the reason I reverted back to 3.8.9 is because 3.9+ did not work (was very slow) in a couple of production clusters. Are there any particular features you are missing in 3.8.9?

• yes, the pom was for me to deploy the jar on my nexus repo. Sorry for the project name change.

• I am actually using jet, coupled with hazelcast+chazel, and anything depending on hazelcast 3.8* seems to get the jet jobs to fail. I get the jet exception below when running a distributed job:

Exception in thread "hz._hzInstance_1_jet.cached.thread-4" java.lang.NoSuchMethodError: com.hazelcast.internal.partition.impl.InternalPartitionServiceImpl.isMigrationAllowed()Z at com.hazelcast.jet.impl.JobCoordinationService.shouldStartJobs(JobCoordinationService.java:551) at com.hazelcast.jet.impl.JobCoordinationService.scanJobs(JobCoordinationService.java:600) at com.hazelcast.spi.impl.executionservice.impl.DelegateAndSkipOnConcurrentExecutionDecorator$DelegateDecorator.run(DelegateAndSkipOnConcurrentExecutionDecorator.java:66) at com.hazelcast.util.executor.CachedExecutorServiceDelegate$Worker.run(CachedExecutorServiceDelegate.java:227)

... hence the update to something in the 3.9 series. I just realized today 3.9.3 was out , tried with that version and things worked smoothly when submitting jet jobs.

sounds good, just fix the pom property and update hz to 3.9.3 I'll merge the pull request

[hellonico]
