The current output for the `--generate` option looks like this
```
Current partition replica assignment
{"version":1,"partitions":[{"topic":"t1","partition":0,"replicas":[0]}]}
Proposed partition reassignment configuration
{"version":1,"partitions":[{"topic":"t1","partition":0,"replicas":[1]}]}
```
This PR simply changes it to
```
Current partition replica assignment
{"version":1,"partitions":[{"topic":"t1","partition":0,"replicas":[0]}]}
Proposed partition reassignment configuration
{"version":1,"partitions":[{"topic":"t1","partition":0,"replicas":[1]}]}
```
to make it more readable.

NPE was caused by `log.logSegments.toArray` resulting in array containing `null` values. The exact reason still remains somewhat a mystery to me, but it seems that the culprit is `JavaConverters` in combination with concurrent data structure access.
Here's a simple code example to prove that:
```scala
import java.util.concurrent.ConcurrentSkipListMap
// Same as `JavaConversions`, but allows explicit conversions via `asScala`/`asJava` methods.
import scala.collection.JavaConverters._
case object Value
val m = new ConcurrentSkipListMap[Int, Value.type]
new Thread { override def run() = { while (true) m.put(9000, Value) } }.start()
new Thread { override def run() = { while (true) m.remove(9000) } }.start()
new Thread { override def run() = { while (true) { println(m.values.asScala.toArray.headOption) } } }.start()
```
Running the example will occasionally print `Some(null)` indicating that there's something shady going on during `toArray` conversion.
`null`s magically disappear by making the following change:
```diff
- println(m.values.asScala.toArray.headOption)
+ println(m.values.asScala.toSeq.headOption)
```

Also:
* Make all implementations of `Time` thread-safe as they are accessed from multiple threads in some cases.
* Change default implementation of `MockTime` to use two separate variables for `nanoTime` and `currentTimeMillis` as they have different `origins`.

The consumer can deadlock on shutdown if a topic event fires during shutdown. The shutdown acquires the rebalance lock and then the topic-event-watcher lock. The topic event watcher acquires these in the reverse order. Shutdown should not need to acquire the topic-event-watcher’s lock - all it does is unsubscribes from topic events.
