* Interface that encapsulates functionality to execute an {@link Operation} with a failover strategy as well.
*
* This class is used when attempting to find a healthy {@link Connection} from a set of {@link HostConnectionPool}(s) for a set of {@link Host}(s)
* This can be used by an extending class of the {@link AbstractHostPartitionConnectionPool} which reliably tries to execute an {@link Operation}
* within the {@link AbstractHostPartitionConnectionPool#executeWithFailover(Operation, com.netflix.astyanax.retry.RetryPolicy)} method for the
* given host partitions.
*
* @see {@link AbstractHostPartitionConnectionPool} for references to this class.
