STORM-1723 (1.x) Introduce ClusterMetricsConsumer
* ClusterMetricsConsumer publishes cluster-side related metrics into
consumers
* like MetricsConsumer for topology metrics
* Users can implement IClusterMetricsConsumer and configure to cluster
conf. file to take effect
* Please refer conf/storm.yaml.example for more details on configuring
* Nimbus should be launched with additional jars which are needed for
IClusterMetricsConsumer
* Also did some refactor to nimbus.clj
I don't address this for master yet since ui/core.clj is not converted to
Java but stats.clj is converted to Java.
If we want to move some methods in this patch to stats.clj, I'll follow up
reviews, and start working on crafting patch against master when patch is ready
to merge.

> for details.
> This issue focuses to introduce ClusterMetricsConsumer and provide interface
> to let users plugin their consumers.
> ClusterMetricsConsumers will be attached to Nimbus, and leader of Nimbus will
> push cluster related metrics to ClusterMetricsConsumer.
> Requirements of ClusterMetricsConsumer are here:
> - Only leader of Nimbus should publish cluster metrics to consumer.
> - Nimbus shouldn't be affected by crashing or heavy latency on consumer.
> - Consumer should have resilient when crashing or Nimbus should take care of.
