Review Request 62423: Improve in-process test ZooKeeper support

-----------------------------------------------------------

-----------------------------------------------------------

Review request for Aurora.

Bugs: AURORA-1947
https://issues.apache.org/jira/browse/AURORA-1947

Repository: aurora

Description
-------

MesosLogStreamModule tries to connect to ZooKeeper servers specified by -zk_endpoints even when -zk_in_proc=true. I updated the module to use injected server endpoints which will be based on the ephemeral port assigned to ZooKeeperTestServer if -zk_in_proc=true. This required to make @ServiceDiscoveryBindings.ZooKeeper public.

I also tweaked shutdown process of ServiceDiscoveryModule.TestServerService so that it won't close existing ZooKeeper connections before clients close the session. While just delaying the execution by 1 second doesn't really guarantee that behavior, in practice this achieved clean shutdown of the scheduler with in-process ZooKeeper server.

Diffs

src/main/java/org/apache/aurora/scheduler/log/mesos/MesosLogStreamModule.java 6704a328a4023a178ed8f86ae4772cb04eb2fa8e

Diff: https://reviews.apache.org/r/62423/diff/1/

Testing
-------

1. Launch Mesos master and slave on my laptop.
2. Launch Aurora scheduler with following arguments:
```
-backup_dir=/var/lib/aurora/backups
-cluster_name=local
-mesos_master_address=localhost:5050
-serverset_path=/aurora/scheduler
-ip=127.0.0.1
-hostname=localhost
-http_port=8081
-zk_in_proc=true
-zk_endpoints=localhost:2181
-native_log_zk_group_path=/aurora/replicated-log
-native_log_file_path=/var/db/aurora
```
3. Observe that there are no ZooKeeper error log outputs caused by missing endpoint.
4. Create a simple job, observer it launches normally and then kill it.
5. Stop the scheduler by sending /quitquitquit.
6. Observe that scheduler process shuts down normally.

Thanks,

Keisuke Nishimoto

This is because zkClientConfig.getServers() here returns values as specified by -zk_endpoints, which is supposed to be ignored when -zk_in_proc=true.  Since ZooKeeperConfig is not injected and we don't know the port of ZooKeeperTestServer when FlaggedZooKeeperConfig.create() is called, it is not trivial to let ZooKeeperConfig#getServer() return a correct value when in-process ZooKeeper server is used.  I may make ZooKeeperConfig#getServers() non-public instead.

While just delaying the execution by 1 second doesn't really guarantee that behavior, in practice this achieved clean shutdown of the scheduler with in-process ZooKeeper server.

    This seems to suggest that `zkClientConfig.getServers()` may return the wrong addresses.  Why is that?
