ZOOKEEPER-2261 When only secureClientPort is configured connections, configuration, connection_stat_reset, and stats admin commands throw NullPointerException Root cause of the issue is that property getter returns the non-secure ServerCnxnFactory instance always. When Quorum SSL is enabled, we set a separate field which is the secure instance. Property getter should detect the scenario and return the proper instance. First commit contains some refactoring: shuffling the existing ZooKeeperServer tests to relevant places. Second commit is the actual fix + new unit tests. Sorry about indentation changes, but `FileTxnLogTest.java` was indented by 2 spaces instead of 4.
