Description

Often integrations should cache and use a shared client for all communication to a given list of masters. This is seen in our own kudu-spark integration in `KuduContext.KuduClientCache`.

It would be nice to add a generic implementation to the kudu-client so that this code doesn't get re-written over and over. Additionally we can add more complex logic if useful later.
