Description: 
Currently, the TracerDriver exposed the latency of ZK operations, in 
multi-tenant environment, extra metrics are required to help tracing and 
monitoring:

* the bytes being sent and received, so we can monitor the client usage 
scenarios.
* which ensemble participant the client is talking to, used to find out the 
problematic Zk server when the issue happened.
* the z-node path, to easily find out which z-node caused the problem, like 
high load, etc.

Description: (was: Allow service instances to be temporarily removed 
from discovery (when using the Service Discovery recipe). 

This can be achieved with a new 'enabled' flag that is included as part of the 
service instance node data in Zookeeper. Updating this flag via e.g. Exhibitor 
will allow an instance to be disabled. When the flag is omitted, the service is 
assumed to be enabled, hence this change is backward compatible.)
