BROOKLYN-545: Fix DynamicCluster.zoneFailureDetector default val
Fixes https://issues.apache.org/jira/browse/BROOKLYN-545
Below is an extract from the comments in the code, explaining it - see
other code comments for more info:
```
// Previously, when there was a mutable default value for
ZONE_FAILURE_DETECTOR, the second cluster
// would include failure info for the first cluster's zone-locations.
When these were unmanaged,
// the zone-locations would become dangling referenes within the
ZoneFailureDetector. This caused
// NPE on rebind.
//
// Config key persistence was then changed so that statically defined
keys (such as ZONE_FAILURE_DETECTOR,
// declared on the DynamicCluster class) would not be persisted. This
meant that the ZoneFailureDetector
// state was no longer persisted for either location. The NPE on rebind
went away, but the config key
// default value instance was still shared between all clusters.
//
// Now the detector has a null default value. We implicitly set a
transient field for the zoneFailureDetector
// so if using defaults then nothing is persisted. But if a custom
ZoneFailureDetector is supplied, then
// that will be persisted and used.
```

BROOKLYN-545: Fix DynamicCluster.zoneFailureDetector default val

> Rebind failure after using cluster with `enableAvailabilityZones`

> Project: Brooklyn
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Aled Sage
> Assignee: Aled Sage
> Priority: Critical
>
> I was running Brooklyn 1.0.0-snapshot. On restarting Brooklyn, it failed to
> rebind with the {{NullPointerException}} below in the log.
> This probably affects lots of older versions of Brooklyn as well (I've
> guessed at 0.12.0 in the "affects" field!).
> Problem is that our xstream deserialization is trying to insert a null key
> into a {{ConcurrentHashMap}}. This is because the {{DynamicCluster}}'s config
> key {{dynamiccluster.zone.failureDetector}} has a mutable default value!
> The {{ProportionalZoneFailureDetector.zoneHistories}} contains
> {{locationProxy}} instances for locations that no longer exist.
> I'm guessing the consequence of this bug is that if anyone uses
> {{enableAvailabilityZones}} in an app and then terminates the app (thus
> unmanaging the locations), any subsequent use of an app with
> {{DynamicCluster}} will cause rebind to fail.
