Also I'm thinking of merging

Health

and

Metrics

classes into

Operations

since the docs mention them under the

Cluster Operations

topic. Something like adding

getHealthStatus

and

getMetrics

functions to

Operations

Not sure if metrics belongs in operations because I can see it becoming more feature rich in future. For health, in future if we provided per node health status etc. again it can either have other actions or atleast take other parameters.
